They prefer renting to owning, shun the suburbs for cities, are likely to live at home with their parents, are putting off marriage and they are well educated. This thesis seeks to study how the living arrangements of the Millennial generation compare to those of the past generations to find out how true this conventional wisdom is. It studies U.S. Census Data from past decades, focusing on the population segment between ages 22 and 31 at each decennial census from 1980-2010. The demographic characteristics of age, marriage and education are studied to determine their influence on the living arrangements of this young adult cohort. Using linear regression models, the propensity to live in different forms of tenure or within a center city of and MSA are parsed out to find what portion of this propensity is due to the delay of marriage, increase in education or changes in the young adult population. The study is then further broken down to determine to what extent changes in living arrangements are due to changes in the preferences of the population versus changes in the demographic composition of the population. From 1980-2010 there has been a decline in the marriage rate and homeownership rate of the population, markedly so amongst young adults. Conversely, there has been an increase in those completing four years of college and the rate of the population living in a home where their parent is the head of household. This study shows that the decline in marriage has reduced the homeownership rate, but there is an increased preference for homeownership amongst those never married especially so amongst young adults. In general there has been a large increase in the preference of young adults to live at home and a decline in the preference to own or rent indicating that those not buying are opting to move in with their parents rather than rent. There has not been an increase amongst Millennials in preference or total propensity to live in center cities. Thesis Supervisor: William C.

As individuals transition from dependent members of households to the formation of their own households, their collective decisions set the landscape for the long-term trends in the housing market. When holding the natural vacancy and scrappage rate of the residential housing stock constant, the need for new residential construction is largely fueled by household formation. Therefore, the trends and preferences in the living arrangements of young adults have a significant impact on demand in the housing market. Recently many articles and studies have focused their attention on the current generation of young adults, commonly referred to as the "Millennial" generation. Specifically, much emphasis has been placed upon how remarkably different they are from previous generations. There are many ways in which the characteristics of this generation differ from their predecessors. They are immersed in technology in ways that past generations could never have imagined. Perhaps as a result of this new world they live in, their social behaviors and attitudes are also very different from those of past generations. This paper will quantify some of these differences through time and determine to what extent changes in the demographic characteristics of young adults influence their living arrangements. 1.1. Millennials and Generational Definitions - Selecting an Age Cohort One particular challenge in studying and comparing generations is the varied definitions of generations. While generational definitions may solidify over time such as has happened with the "Baby Boomer" generation, this has not yet occurred for the Millennial generation. Definitions of this cohort by birth year may range from 17 years (1981-1997) (Fry, This year, Millennials will overtake Baby Boomers, 2015) to 23 years (1980-2004) (Hoover, 2009). This paper will focus less on the generational definition and instead will adopt a definition of "young adults" that is normalized through time to compare the Millennial generation to the past. 7 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults To establish a cohort to analyze, it is important to consider the goals of the study. This paper will use data from the United States Decennial Census and the American Community Survey (collectively referred to as "Census Data") to compare a specific age bracket. The lower bound of the age bracket is set at 22 to ensure that the cohort will include those that have typically moved on from living with their parents as well as those that have typically completed a bachelor's degree if they have pursued one. The upper bound is set at 31 so that for each decennial census there is no overlap as the cohort includes a decade-long span of birth years. The data to be compared will include the 1980-2000 U.S. Census and the 2010 American Community Survey. The birth years will for each cohort sample will include 19491958 (Older Baby Boomers), 1959-1968 (Younger Baby Boomers/older Generation X), 1969-1978 (Generation X), and 1979-1988 (Younger Millennials). 1.2. Millennials and Marriage In the primary housing market, demand increases by the net formation of new households. The formation of new households is driven by young adults leaving their parent's home and establishing their own. While, the term household may elicit the image of a married couple starting a family, there are many forms of households and increasingly fewer of them include married couples. Although one may think the reduction in marriage of young adults would have a great effect on net housing demand, its effect is relatively minimal as long as the individual leaves their parent's home. In the absence of marriage young adults typically form a different type of household by "doubling up" with a roommate. There is, however, an expected effect of changes to the marriage rate on housing tenure. The majority of households that are headed by a married couple have children, and vice-versa. While there may not be a presumed correlation between the rate of marriage in young adults and the overall demand for housing, it is understood that there is a correlation between having children (and thus marriage) and housing tenure (DiPasquale & Wheaton, 1996). It can be expected that a delay in marriage would bring about a delay in child bearing and a resultant delay in homeownership. 8 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults There has been a significant increase over time in the median age at which Americans first marry. As shown in Figure 1-1, this increase began in the mid-1970s and has increased by 3.5 years for men and 4.5 years for women during the 1980-2010 study period (U.S. Census Bureau, 2011). While there is no single reason for this trend, polls suggest a few key factors in not marrying. In recent years amongst those never married, the top three reasons for not marrying were selectivity, age, and financial considerations. (Gallup, 2013) Although there has been a resultant increase in the median age of first marriage, most young adults still desire marriage. In 2013, amongst Americans ages 18 to 34, only 9% indicate that they do not ever want to be married. (Gallup, 2013) If this is in fact true, it is expected that any decline in the homeownership rate due to the increase in delay of marriage may create an increase in the demand for homeownership in the future.

Millennials and Education Two major trends in education impact the current generation of young adults in a way that their predecessors did not face. In 1980, 17% of adults 25 and older had completed four or more years of college. In 2010, this rate increased to 29.9%. (U.S. Census Bureau, 2015) Additionally, the cost of education has increased significantly. Adjusted for 2014 dollars, the average annual cost of tuition and 9 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults fees for a four year nonprofit private college has almost tripled from 1980 to 2010. (College Board, 2015) The combination of these two trends results in an even greater level of income that must be devoted to paying for education. Increasingly this cost is paid with some sort of loan as the percent of bachelor's degree recipients graduating with education-related debt has increased from less than 50% in 1993 to almost 70% in 2010. (Kantrowitz, 2014) Adjusted for 2012 dollars, this has amounted to an increase in the total amount borrowed for higher education from $24 billion in 1990-91 to $110 billion in 2012-2013. (Baum, 2013) While this additional educational attainment will result in an increase in lifetime earning power for degree recipients, the portion of the income of young adults that must be devoted to paying down college loans has also increased. This again suggests that young adults may initially be hampered by college expenses, but in the future when their debt has retired they will be financially ready for homeownership if they desire.

Millennials and Housing Tenure It has been noted that the current generation of young adults are less likely to own a home than their predecessors. While there are many reasons for a shift away from home ownership amongst young adults, polls have shown that most young adults still expect to eventually own a home. (Lachman, 2015, 10 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults p. 23) The reduced propensity of young adults to own a home as well as their expectation of eventually owning a home are similar to the trends and preferences of this cohort towards marriage. When considering future housing, the attribute young adults place the most emphasis on is cost. (Lachman, 2015, p. 26) While young adults exhibit a desire to own a home, they may simply lack the financial ability to do so. The majority of young adults rent their home. Amongst young adults who rent, the most appealing characteristics of renting are lack of maintenance responsibilities and flexibility/commitment considerations. This would indicate that an increase in the rate of young adults who rent may represent and increased desire for flexibility and a reduced desire to spend time maintaining their home. 1.5. Millennials and the Suburbs: Returning "Home" Perhaps one of the more widely discussed characteristics of the Millennial generation is the increased likelihood that they will either continue to live in their parent's home as young adults or they will return to and remain at their parent's home after attending college. Approximately 21% of Millennials as defined by ULI live with their parents, mostly for financial reasons. (Lachman, 2015) The steep decline in the marriage rate of Millennials has also been credited as a contributor to the trend of living at home. (Fry, A Rising Share of Young Adults Live in Their Parents' Home, 2013) When considering housing tenure, statistics are typically broken down into ownership versus renting. For the majority of the population, these are the only two choices considered. However, with the increased rate of young adults living with their parents it truly represents a third choice for this age group. For the purposes of this paper, these three living arrangement choices shown in Figure 1-3 are called "Total Tenure" because only studying the tenure choices of renting versus owning would leave out a significant portion of this group. Given that the portion of the population living at home is largely doing so for financial reasons, one may expect that this would have the greatest impact on the propensity to rent as this segment of the population traditionally would not have the means to purchase 11 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults a home. However, the percentage of young adults renting has held steady and the increase of young adults living at home with their parents has coincided with a decrease in home ownership amongst the cohort. What is unclear is if this is a result of "trickling down" of tenure (those who in the past would own now rent and those who in the past would rent live at home) or if many folks are living at home as a means of saving up for a home purchase.

Millennials and Urban Dwelling Millennials are known for shunning the suburban life of past generations for dense urban neighborhoods. While a recent study indicates that young adults have no greater propensity to live in the downtown "core" of a center city, it does show that there is a greater desire to live within the outer areas of a center city. (Lachman, 2015, p. 4) Conversely, a different survey however shows that 66% of Millennials want to live in the suburbs. (Hudson, 2015) These conflicting results suggest that preference polls may not be the best way to study the locational propensity of the cohort. 12 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults 1.7. Thesis Intent and Hypothesis While most studies and preference polls focus on the short term trends of the current market, this thesis intends to compare the characteristics of the current population of young adults to past generations of the same age. Rather than taking a snapshot of preferences, it will look at long-range shifts in propensities. It will first look at the housing characteristics of young adults over time including tenure and location using survey data from the U.S. Census. Then it will study two key demographic features in education and marriage rate. It is expected that over time, changes in education level and marriage rate will have an influence on housing tenure and location. Additionally, it is expected that over time that simply being a young adult will have a similar influence. Using these two key demographic qualities along with studying the cohort of young adults, this thesis will identify to what extent changes in housing tenure and locational preference are derived from these characteristics. It will then parse out the changes to determine to what extent they are a result of preferences of the population or the demographic complexion of the population. It is expected that changes in the preferences will have a more dynamic impact on the outcome than will changes in the population mix. 13 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults Chapter 2: Census Data 2.1. Data Source This thesis will study microdata samples from each of the decennial U.S. Censuses from 19802000 as well as the 2010 American Community Survey (ACS) to search for trends and correlations amongst select characteristics of the entire U.S. population. (Ruggles, et al., 2010) This data is available from the Integrated Public Use Microdata Series (IPUMS-USA) in the form of microdata, which are not a collection of statistics, but rather are samples of individual records from Census Data. By using samples of individuals rather than tabulations, one can use statistical software to analyze millions of individual records focusing on selected characteristics of their choosing. 2.2. Data Overview A challenge in using IPUMS data is the inconsistent availability of certain variables and changes in the construction of the samples over time. For example, the acreage of a property is only available from 1960-2000 so if one is conducting a study focused on property size, they are limited to focusing on that specific timeframe. From 1850-2000, the samples are taken from the decennial U.S. Census. While most of these samples represent 1% of the total population, from 1980-2000 a 5% sample was taken. Unfortunately, a 5% sample has not yet been made available for the 2010 Census. From 2000-2013, the available data is only from the ACS. The ACS data is not robust from 2000-2004 as it typically only includes a 0.4% sample. However from 2005-2013, the sample size increased to 1%. Although it would be preferable to consistently work with a 5% sample for all 4 periods from 1980-2010, the variables to be studied apply to a large portion of the population so using a 1% sample will not produce a significant distortion in results when compared with the 5% samples. This paper will limit its focus to the three "total tenure" choices described previously, the propensity to live in center cities, the delay of marriage, and the education level of young adults as it 14 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults compares to the remainder of the adult population as well as past generations. Most of these choices are derived from the IPUMS data detailed in Table 2-1.

These dummy variables are binary indicators in that they either have the value of 1 indicating that an individual includes the defined characteristic or 0 meaning they do not include that characteristic. Additionally, the dummy variable "MILLENNIAL" was created using individuals of the ages 15 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults of 22-31 for simplification of analysis. The dummy variable "CITYDUM" applies only to the subsample described in section 2.3.

To do so, one must find a variable that represents whether the best lives in an urban area that is consistent for all of the data samples to be studied. Perhaps in which an individual metric for identifying a location as urban is the population density of the location Public Use lives. While density is not an available variable, for the year 2000, the area of an individual's samples, Microdata Area (PUMA) is available. The PUMA is the smallest geographical identifier of later area, one but the 2000 PUMA definitions are only consistent for the years 2000-2011. Using the PUMA area but could construct a density variable for the data by dividing the PUMA population by the PUMA this variable would not be applicable to samples outside of the years from 2000-2011. as it The variable "METRO" within the IPUMS data would be particularly useful for this purpose if so does that identifies whether or not an individual lives in a Metropolitan Statistical Area (MSA) and requirements individual live in the center city of that MSA. Unfortunately due to both the confidentiality (See Figure 2of the sample as well as the geographic identifiers of the data, this variable is incomplete. MSA, it cannot be 1) For some individuals, this variable is either not identifiable or if they are within an in the 1% Sample for determined if they are in the Center City. Additionally, this variable is only available 1990. 16 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults IPUMS 'METRO' Variable Tabulations Source: U.S. Census Data Tabulations, IPUMS-USA, University of Minnesota 100% 80% 60% 20% 20% 19901% 19805% a Outside City o Metro Undefined E Central City Figure 2-1 - 20005% Non-Metro 2010 ACS 0 Not Identifiable IPUMS 'METRO' Variable Tabulations 2.3. Center City Definition and Selection of MSAs For several cities, the "CITY" variable is not identifiable for many or all sample years. This is also true for the "METAREA" variable for many small MSAs. This inconsistency and incompleteness is a result of PUMA definitions. In many cases, a PUMA boundary straddles a municipal boundary so it cannot be determined which side of the boundary the individuals within a PUMA reside. These individuals are either tagged as "Not identifiable" or "Metro Area Center City Status Undefined" Where this occurs at a city boundary, a 10% threshold for error of inclusion or exclusion is allowed meaning that the city variable may slightly overestimate or underestimate the population of specific cities. If this error exceeds the 10% threshold, the city in question is deemed unidentifiable for that sample. In the case of MSA boundaries, any PUMA that straddles a boundary is excluded and determined to be not identifiable resulting in an underestimation of the population of some MSAs. In some instances this underestimation is very significant. For select MSAs, the Center City is identifiable for all years from 1980-2010. Ideally a sample identifying the Center City status would include the entire U.S. population, but this is not possible. However, if a sufficient number of major MSAs are included, a meaningful study of the propensity to be located in the Center City of an MSA can be conducted. Within this group of MSAs with identifiable 17 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults Center Cities, a number have a relatively low portion of the MSA that is excluded as it is not identifiable. In some cases of the 1980 or 1990 sample for certain cities, the 1% sample must be substituted for either the city population, the outer MSA population or both. For this paper a set of 47 MSAs have been established for study in which the Center City is identifiable and no more than 9% of the MSA is excluded for all study years.

For the study years, these MSAs represent on average 41% of the total U.S. Population. With this constructed data set, the members of the data set that live in a Center City versus the outer MSA can now be identified. These MSAs are 18 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults extracted into a separated data set, substituting 1% samples for specific cities during specific years only when necessary. The variable METRO is recoded within this set so that the "Central City" indicator applied to all members living only within the most major city of the MSA. All other individuals in the MSA are coded as "Outside of Central City".

Linear Regression Methodology - Simple single linear regression of data To begin to understand the most basic trends in the demographics and housing arrangements of the adult population of the samples, one must start by understanding the propensity of the 22-31 study cohort to include the characteristics of concern. One way to understand the probability of this cohort to include a characteristic is through a very simple linear regression of the following equation form: y =oc +flx, where: y = Probabilitymember of population is "y" x = Member of population is ages 22 - 31 oc= Intercept (Probabilitypopulation > age 31 is "y") fl = Coefficient if age is 22 - 31 With the exception of income, all of the following variables are binary values. For example, one has either been married before or they have never been married. The value of y cannot be less than zero or greater than one. Typically, this calls for the use of a logistic function and therefore a logistic regression with odds ratios for an outcome. However, it has been shown that a linear regression might not only be useful but also preferable in some cases where the dependent variable is a binary. (Hellevik, 2007) This preference for a linear regression will apply to this study as the independent variables used will also be binary and the sample size is very large. The data will be analyzed using the Stata 14 software. (StataCorp, 2015) For the full sample data, the svyset command is been used to account for stratification and clustering using the STRATA and CLUSTER variables. The simple regressions are performed to compare the 22-31 cohort to the total adult population over age 22. 20 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults 3.2. Delay of Marriage The first regression compares the NEVMARRY variable as a dependent with the MILLENNIAL variable as the sole predictor variable. This regression is performed for each year and the results are shown in Figure 3-1. Note that "Total Population" refers to all individuals over age 22, inclusive of the age 22-31 cohort. Never Married 70.00% 60.00% 50.00% 40.00% 30.00% 20.00% 10.00% 0.00% 1980 1990 a Total Population 2000 2010 N Population Ages 22-31 Figure 3-1 - Percentage of Population Never Married The results of this first analysis are quite remarkable and clearly reflect the trend in delaying marriage in the population. Since 1980, this statistic for young adults has nearly inverted where once only 32% of young adults had never been married. In 2010 62% of young adults had never been married meaning only 38% of the cohort has ever been married. The approximate 30% change in young adults having never been married took its two greatest steps in 1980-1990 (10%) and 2000-2010 (14%). 3.3. Education Level The next regression compares the BACHELORS variable as a dependent with the MILLENNIAL variable as the sole predictor variable. The results are shown in Figure 3-2. 21 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults 4 Years of College Education 30.00% 20.00% 10.00%j 0.00% 1980 1990 0 Total Population 2000 2010 * Population Ages 22-31 Figure 3-2 - Percentage of Population That Has Completed Four Years of College While in 1980, there is a relatively large gap in the education level of young adults compared with the total population, by 1990, the statistic has levelled off to the point that both young adults and the total adult population have essentially the same probability of having completed 4 years of college. 3.4. Personal Income This regression compares the only continuous variable studied INCTOT, which is an individuals total personal income. With INCTOT as a dependent with the MILLENNIAL variable as the sole predictor variable, we can see how the income level of young adults has changed through time relative to the total adult population when adjusted for the CPI of 2000 using the CP199 variable. The results are shown in Figure 3-3. The income gap between young adults and the total adult population is relatively small in 1980, and it grew steadily until 2000. Presumably, the drop in income levels exhibited in 2010 are resultant from the great recession of 2008-2009. This change has a greater impact on young adults as the total population income levels are still greater than those of 1980 and 1990, while the income of young adults is reduced significantly from historical levels. 22 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults Mean Personal Income (CPI Adjusted to Year 2000) $35,000 $30,000 $25,000 $20,000 3 7 $10,000 $5,000 1980 2000 1990 n Total Population a Population 2010 Ages 22-31 Figure 3-3 - CPI Adjusted Mean Personal Income 3.5. Home Ownership The following regression compares the OWN variable as a dependent with the MILLENNIAL variable as the sole predictor variable. The results are shown in Figure 3-4. Home Ownership 70.00% 60.00% 50.00% 40.00% 30.00% 20.00% 10.00% 0.00% 1980 1990 mTotal Population 2000 2010 a Population Ages 22-31 Figure 3-4 - Home Ownership Rate of Total Population Age>22 vs Age22-31 Cohort While home ownership levels for the total population have held relatively steady for the adult population, the rate has fallen by almost 14% for young adults from 1980-2010. Similar to the marriage statistic, the greatest changes are seen in 1980-1990 (7%) and 2000-2010 (6.6%) 23 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults 3.6. Renting To study the trends in the propensity to rent for young adults, a regression of the RENTER variable as a dependent with the MILLENNIAL variable as the sole predictor variable is performed. The results are shown in Figure 3-5. Rental Tenure 50.00% 45.00% 40.00% 35.00% 30.00% 25.00% 20.00% 15.00% 10.00% 5.00% 0.00% 1980 1990 MTotal Population 2000 2010 * Population Ages 22-31 Figure 3-5 - Rental Tenure Rate of Total Population Age>22 vs Age22-31 Cohort Interestingly, in spite of all of the changes within the population and specifically the young adult cohort, the propensity to rent for both young adults and the total population has held steady. 3.7. Increase in Living with Parents Next, a regression of the ATHOME variable as a dependent with the MILLENNIAL variable as the sole predictor variable is performed. The results are shown in Figure 3-6. Similar to both the delay in marriage and the decrease in home ownership amongst young adults, there has been a large increase of 11% in the number of young adults living with their parents with the greatest increases occurring from 1980-1990 (4.4%) and 2000-2010 (7.8%). There is almost a 1% drop in this rate from 1990-2000. 24 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults Living at Home 30.00% 25.00% 20.00% 15.00% 15.00% 10.00% 10.00% 1980 1990 0 Total Population 2000 2010 w Population Ages 22-31 Figure 3-6 - Rate of Living with Parents Total Population Age>22 vs Age22-31 Cohort 3.8. City Living Finally, a regression of the CITYDUM variable as a dependent with the MILLENNIAL variable as the sole predictor variable is performed. This is performed using a standard linear regression as the complete survey set of data is not included. The results are shown in Figure 3-7. Center City of MSA (Select Areas Only) 40.00% 35.00% 30.00% 25.00% 0 20.00% 15.00% 10.00% 5.00% 0.00% 1980 1990 a Total Population 2000 2010 N Population Ages 22-31 Figure 3-7 - Rate of Living in Center City of MSA Total Population Age>22 vs Age22-31 Cohort Overall, the concentration of the total population in the center city relative to the total MSA has declined over time. This is to be expected as MSA definitions typically expand over time to include outer 25 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults areas while the city boundaries remain fixed. In spite of MSA expansion, the concentration of young adults in the center city has held fairly steady. 26 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults Pooled Multiple Linear Regression Analysis Chapter 4: With the basic relationship of the defining characteristics to the young adult cohort established, the relationship of the demographic variables to the housing outcomes will now be explored. First we will pool the data for all four census samples to see what impact the changes to the population mix by marriage rate, educational attainment level and being a young adult have on housing outcomes. 4.1. Methodology A multiple linear regression model will be created again using only the binary independent variables MILLENNIAL, NEVMARRY and BACHELORS to predict the dependent variables: OWN, RENTER, ATHOME, and CITYDUM. The results will determine the average preference towards a specific housing outcome resultant from the combination of these different independent characteristics. 4.2. Regression Equation - Impact of changes in demographics on housing of Total Population The multiple linear regression equation for the total adult population will take the form: y 1x 1 + l2x 2 + f3x 3 fO + = y = Probabilitymember of population is "y" x= Member of populationis ages 22 - 31 X2= Member of populationhas never been married Member of populationhas attended 4 or more years of college f 0 = Intercept (Probabilityfor pop > age 31, married,and not coll. educated "Pure Cohort") X3= f 1 = Preference Coefficient if age is 22 - 31 # 2 = = fl PreferenceCoefficient if person has never been married PreferenceCoefficient if person has attended 4 or more years of college #3xa fx = BX h, + ?1x1 + Preference = [fl 0 f1 N 2 f3] = [Other Chort Never Married 4 Years of College] Total Population 1- Vector form: y = B = T =Cohort Population y = BXT Ay = BXT -BXT-1 Ay = B[Xr - Xr- 1 ] 27 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults 4.3.

Home Ownership To identify how the changes in the demographic mix impact the home ownership rate over time, we start with the Ay = B[XT - XT-1] vector equation from above. From this, we can decompose the changes in home ownership rate from decade to decade based on the changes to the combination of these characteristics while using the average preference B over this time period. Tables 4-la & 4-1b detail these results.

This will be the case for most of the following analyses. For both young adults and the total population, having never married produces a strong negative impact on the home ownership rate for all periods. From 1980-2000, being a young adult increases the likelihood of home ownership, but this diminishes in 20002010. Having completed 4 years of college has a steady impact of a 0.4% rate increase from decade to decade for the total population. The impact of a college degree on the home ownership rate is positive for young adults, but it only begins to trend upward in a significant manner in 1990. 4.5. Renting Continuing with the same format Tables 4-2a & 4-2b show the effects of the independent variables on Rental Tenure. For the total population, the preferences from the regression analysis produce a relatively good fit, reflecting the relatively minimal and steady change in the rental rate. Again college education has a steady impact on rental rate. This is likely more reflective of the steady increase in the education rate of the population than any other reason. Being a young adult has a negative impact on the rental rate while never marrying had a positive impact. These effects cancel out from 1980-1990, while from 1990-2000 the impact of being a young adult is greater. This then shifts considerably towards the rate of never marrying, reflective of the change in in this rate. 29 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults Table 4-2a Components Other Effects Young Adult Never Married Bachelor's Degree ARenter from Change in Mix (Adults 22 and Over) Population Change Rate Change 1990-00 1980-90 2000-10 1990-00 1980-90 5,429,755 5,500,808 0.00% 0.00% 0.00% (447,908) 308,250 -0.12% -0.75% -0.48% 749,923 1,057,359 0.58% 0.14% 0.40% (673,223) (582,727) -0.21% -0.21% -0.22% 2000-10 5,331,800 549,396 1,759,191 (757,645) Predicted Change -0.30% -0.82% 0.26% 6,283,690 5,058,548 6,882,741 Actual Change 0.51% -1.00% 1.03% 7,468,215 4,719,034 8,516,868 Prediction Error -0.81% 0.18% -0.77% (1,184,525) 339,514 (1,634,127) For the young adult regression, the prediction is far off from the actual changes suggesting that factors not considered in this model are likely responsible for the changes.

Living with Parents Tables 4-3a & 4-3b show the effects of the independent variables on Living at Home. As one would expect in both cases there is a strong positive correlation between never marrying and living at home. Having a Bachelor's degree and being a young adult has a slight negative impact on the rate change. Among young adults, the negative impact of a Bachelors degree is only present to a significant degree starting in 1990 and the trend mirrors the impact of education on homeownership. 30 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults Table 4-3a Components AAthome from Change in Mix (Adults 22 and Over) Population Change Rate Change 1990-00 2000-10 1980-90 1990-00 2000-10 1980-90 Other Effects Young Adult Never Married Bachelor's Degree 0.00% -0.27% 0.71% -0.12% 0.00% -0.41% 0.25% -0.12% 0.00% -0.06% 1.03% -0.11% 406,392 170,803 1,879,650 (320,885) 401,143 (248,188) 1,333,127 (370,717) 393,906 304,424 3,127,287 (417,206) Predicted Change 0.32% -0.28% 0.85% 2,135,961 1,115,364 3,408,411 Actual Change 1.27% -0.63% 2.18% 3,512,024 429,204 6,186,658 -0.95% 0.35% -1.32% (1,376,063) 686,160 (2,778,247) Prediction Error Table 4-3b AAthome from Change in Mix (Adults 22-31) Population Change Rate Change 2000-10 1990-00 1980-90 2000-10 1990-00 1980-90 270,762 (220,745) 151,917 0.00% 0.00% 0.00% 2,161,525 311,021 1,422,087 4.09% 1.66% 3.05% (169,836) (80,557) -0.25% (51,245) -0.32% -0.05% Components Other Effects Never Married Bachelor's Degree Predicted Change 2.99% 1.33% 3.84% 1,522,758 9,720 2,262,452 Actual Change 4.35% -0.91% 7.75% 2,064,918 (865,113) 3,836,370 -1.36% 2.24% -3.91% (542,160) 874,833 (1,573,918) Prediction Error 4.7.

Regression Equation Fit The fit of the regression equations are fairly poor when compared to the actual rate of change from year to year. In most cases, it reflects the cyclical nature of the actual results, but the amplitude of the change is muted. This is likely because although the rate of change in marriage delay is somewhat cyclical from 1980-2010, the equation is only accounting for that rate of change and not the rate of change in preferences relative to marriage delay the other independent variables. Additionally, when applied to the rate change, this model only accounts for the independent variables studied and neglects to include a term for other unknown effects. This is because although there is a "Pure Cohort" term in the equation, it is cancelled out as flo is constant and x0 = 1. To resolve this and develop a better fit, we will run the regressions independently for each decennial sample set accounting for the changes in the B vector allowing both for better accounting for changes in effects over time and the inclusion of rate of change in other effects not studied. 32 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults Individual Multiple Linear Regression Analysis of Decennial Data Chapter 5: As demonstrated in the previous chapter, a regression of the data for all of the decennial data samples provides some insight into the components of the rate of change in living arrangements. Holding a constant coefficient for effects (B), and applying it to the change in composition of the population( X, - XT_-), yields a somewhat inaccurate prediction of the various rate changes. To obtain a more accurate prediction both the change in composition of the population (XT - XT-1) and the change in the effects of various characteristics (BT - BT-1), must be assessed. 5.1. Methodology The same multiple linear regression model from Chapter 4 will be created again, only this time it will be run individually on each sample to obtain separate BT vectors. The results demonstrate the effect that the change in the independent characteristics combined with the change in the effects of those characteristics over time have on housing outcomes. 5.2. Regression Equation - Separating impact of changes in demographics vs changes in effects The same equations used in Chapter 4 will remain only this time the B vector will have the subscript T, denoting the change in B for each year. = [Wb I1 f 2 f3 ]r = [Pure Cohort 1 xT =Cohort Total Population Population Population Never Married X2 XX Chort Never Married 4 Years of College]T - Br T .Populationwith 4 Years of College- y = BrXT Now the equation for the change in y, will include the change in B.

Sources of Change - Total Population The following term represents the portion of the change in rate of y that is a result of a change in X from year to year (change in population mix): BT[XT - XT-1] For the total population, this includes the change in the percent of the total population that is a young adult, never married and/or has completed four or more years of college. In vector form, it is expanded as: r'1- XT-Xr=x, 1 Total Population _ Cohort Population xl X2 X2 -X3- T -X3- T-1 PopulationNever Married [Populationwith 4 Yrs College.

Home Ownership When comparing the decade-to-decade changes in the homeownership rate, a much better picture of what is driving the changes can be seen using separate regression analyses for each sample set. In Table 5-1a and all subsequent tables, the portion of the change resultant from the known differences in the population composition is in the "Mix" column while the portion of the change resultant from the difference in the characteristic effects (preference factor) is in the "Pref." column. The intercept value for other effects is omitted from the prediction. From this we can see the total predicted changes resultant from the studied effects. When considering the intercept value, there is little actual error, so the bottom line number in the following tables should be considered the total change due to other unknown effects.

What is clear is that the difference between the actual rate change and the predicted rate change in Table 4-1a is a result of the change in preference effects. The ownership preference of those with college education has steadily grown. "Other Effects" make up the greatest portion of the change in the declining periods of 1980-1990 and 2000-2010. Table 5-1b AOwn from Change in Mix and Preferences (Adults 22-31) 2000-10 1990-00 1980-90 Components Mix Pref. Mix Pref.

The relative preference of those being never married has a surprisingly positive effect on homeownership as shown in Table 5-1b, but the dramatic shift away from marriage results in a net reduction in the homeownership rate. While the change in population that has never married has a large effect on the change in the homeownership rate, there are other effects that have an even greater impact. 5.7. Renting As shown in Table 5-2a, the effects of being never married, having a bachelor's degree and being a young adult has a combined 1.6% negative effect on the change in renter rate from 2000-2010. This is cancelled out however by the 2.5% positive impact of other effects. Recall Table 4-2b demonstrates that changes in the characteristics of the population of young adults does not explain the 36 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults change in rental rate of young adults. In reality, there are increases in the rate both from 1980-1990 and from 2000-2010 and a decrease from 1990-2000, but the model suggested little to no change in the rate for all 30 years.

Interestingly, changes in the composition of the population generally play an insignificant role in the rate change. The change in preference creates essentially all change in the rental rate of young adults. Much of this is resultant from other effects, but the effect of marriage plays a differing but significant role.

Living with Parents While delay in marriage has the largest impact on the change in rate of adults living with their parents, from 2000-2010, the preferences of young adults plays the largest role. This means that it became more likely for a young adult to live at home than in previous years as is shown in Table 5-3a.

However from 1990-2000, the preference of those never married to live at home decreases so significantly that on whole, never marrying results in a 2% decrease in the rate. This occurs in spite of a steady increase in the rate of marriage delay. From 2000-2010, this preference disappears while other effects results in a substantial increase of 4.6% in this rate.

Living in Center City of MSAs In Table 4-4a, there is a disconnect between the predicted population-based rate change and the actual rate change in the concentration of populations in the center cities of an MSA. By just using education and marriage as a predictor, a flat to very slightly positive change in the rate is expected. However, as Table 5-4a shows, there is a consistent decline in the rate of approximately 3% per decade resultant from other effects. The there is no change in the effect of never marrying, so only the change in the rate of marriage itself has an impact. The effect of college education has a greater impact from 2000-2010. A change in the preferences of young adults only occurs from 1990-2000 as there was a 1% increase in the rate from that preference during that period.

(Kolko, 2015) This can be seen in the 1.4% rate increase resultant from both the population change and the preference effect change of those with a bachelor's degree. 40 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults Chapter 6: Results Summary 6.1. Change in Home Ownership For the total adult population in the U.S., the change in homeownership rate exhibits a decline from 1980-1990 (-2%), an increase from 1990-2000 (+1.4%) and it again a decline from 2000-2010 (2.8%). This oscillating pattern is exhibited in many of the studied characteristics. In the down years, it can be explained partially by the change in the rate of never marrying (-0.8%/+0.1%/-1.3%) and in 19902000 the increased population of young adults has a positive impact not seen in the other periods (0%/+1%/0%). The impact of having a bachelor's degree rose slightly (+0.6%/+0.8%/+1.3%). Similarly, for young adults the change in ownership rate oscillates from -7% to -0.8% to -6.6%. As is the case for the total adult population, never marrying accounts for a portion of the rate of decline (1.5%/-0.2%/-2%) but it is influenced to a greater extent by other effects. 6.2. Change in Rental Tenure For the total adult population, the rental rate changes are opposite of the ownership rate changes. The changes are smaller (+0.5%/-1%/+1%) than that of the ownership rate. Having never married always increases the propensity to rent, however this rate oscillates (+0.2%/+1.2%/+0.2%) like many of the other trends do in this study. The impacts of other effects oscillate and are significant from 2000-2010 (+1%/-0.7%/+2.5%). For young adults, the change in rental rate increases steadily from 1980-2000 and then declines from 2000-2010. The overall changes in rental rate of the cohort are relatively modest (+1.9%/+1.4%/0.9%), but this hides significant changes in the preferences of those who have not married to rent their home. This preference oscillates significantly (-1.6%/+3.5%/-3%) however it is largely offset by other unknown effects (+3.3%/-2.1%/+2.8%) resulting in a deceivingly steady rental rate for the cohort. 41 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults 6.3. Change in Living at Home The change in rate of adults living at home oscillates similarly to the change in rate of renting, but with greater amplitude (+1.3%/-0.2%/+2.2%). While the preference of those never married has steadily trended away from living at home with their parents, this has been offset to some extent by the increase in the volume of people that are never married. On the whole, never marrying has a net positive effect from 1980-1990 (+0.6%) and 2000-2010 (+0.6%). The net effect is negative from 19902000 (-0.8%). The preference of young adults to live at home increases from 1980-1990 (+0.5%) and 2000-2010 (+1.1%) and holds steady from 1990-2000. Other effects are steadily increasing (+0.6%/+0.6%/+0.8%) Within the young adult cohort, the results are fairly similar except that unknown other effects increases dramatically by +4.7%. The preference of those never married oscillates similarly but with greater amplitude and the volume of individuals never marrying increases the rate greatly for all periods (+3.4%/+1.4%/+3.5%). Generally, the education level of the young adult cohort played an insignificant role in the rate change for all periods. 6.4. Central City Concentration The concentration of adults in center cities has steadily decreased relative to the total population of an MSA. Although there is a consistently negative trend (3%/-2.3%/-1.7%), other effects make up the majority of this trend (-3.2%/-3.4%/-2.8%). This is likely a result in the expansion in the definition of MSAs relative to their center cities. Ignoring these other effects, having never married consistently increases the likelihood of living in the center city (+0.5%/+0.1%/+0.8%), while having a bachelor's degree has steadily grown in its positive impact (-0.2%/+0.1%/+0.5%). Most notable in this study is the change in the preference of young adults to live in center cities. This preference only increases from 1990-2000, while it was generally flat or decreasing in other periods. (-0.3%/+1.0%/-0.1%) This shows that the preference of Millennials to live in center cities is 42 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults slightly less than that of Generation X and that it was Generation X that generally had a greater preference for living in center cities than their predecessors. This preference amplifies when studying the cohorts alone. Amongst this age group, the rate change oscillates (-2.6%/+1.3%/-0.7%) rather than staying steadily negative as it is for the total adult population. While this trend is mostly driven by other effects (-2.9%/+0.5%/-3.1%), this is counteracted a bit by those never marrying (+0.7%/+0.1%/+1%). As was the case for the total population, the impact of education grows steadily and to a greater degree (-0.3%/+0.6%/+1.4%) 6.5. The Impact of Changing Marriage Rate As expected, the change in the marriage rate of the population generally has a negative effect on the home ownership rate as shown in the "Mix" column of Table 6-1a. However, this shift in the population is as likely or more likely to increase the rate of the population living at home than the portion of the population renting.

This is mainly due to changes in the population as there is an unintuitive increase in the preferences towards home ownership from young adults never marrying. This positive effect is much smaller than the impact of the large increase in the number of individuals not marrying, which has a large negative effect on ownership. When looking at just the most recent cohort, the preference of those never marrying is significantly negative on the rental rate, but this looks is if it may be more of a mean reversion for the preference as it is strongly positive for the previous period. In general, the change in marriage rate increases the rate of the population living at home while reducing the ownership rate. It is likely that this will have a lasting impact on the rental market if the delay in marriage has made it more culturally acceptable to live at home. Even when the proportion of the population that is never married stabilizes, if the propensity to rent amongst those never married does not increase, there will be a lasting shift in the rental rate of young adults. 6.6. The Impact of Increased Educational Attainment The proportion of the population completing four years of college education has steadily increased over the last three decades. This trend has had a continual positive impact on the home ownership rate in the U.S. and a negative impact on the rental rate. As shown in Table 6-2a, this increase is this increase is a combination of both the increase in the educated portion of the population and an increase in the positive impact of education on home ownership.

As shown in Table 6-2b, there effect in the young adult cohort was somewhat minimal until 2000-2010. Another difference in the cohort when compared to the total adult population is the role college education plays in the propensity to live at home. Perhaps this is because the cohort is simply more likely to live at home, but it does show that the role student debt plays in living at home may not be significant.

When looking at the preference shift amongst young adults from 2000-2010, it is clear that the home ownership rate is declining significantly from changing preferences (-3.1%) and the preference to rent is also declining slightly (-0.9%). The preference to live at home is increasing significantly (+4.5%). It is clear that the decline in homeownership is resultant from a preference to live at home. 45 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults Table 6-3b Tenure Type Ownership Renting Living at Home Complete Total Tenure Shift (Adults 22 1990-00 1980-90 Mix Pref.

While the homeownership rate amongst young adults has continually declined from 1980-2010, the decline was most significant in the 1980s and the 2000s. Within these two periods, the delay of marriage accounted for a portion of this change (-1% and -2% respectively to the total rate). There are other factors influencing this change in both periods and in both cases these other factors resulted in a greater than 5% decline in the homeownership rates amongst young adults. It would be useful to examine whether the factors include access to credit, debt load or other changes. What is also clear is that the decline in homeownership has had a relatively minimal recent impact on the rental rate amongst young adults. This is entirely a result of the strongly decreased preference for renting amongst young adults who have never married. This would give credence to the theory that some portion of young adults are delaying marriage as a result of a greater preference for homeownership than renting. These young adults are moving back in with their parents in hopes of eventual home ownership. Finally, there is not a large push for young adults to move into center cities. There is an uptick in the composition of young adults in center cities with bachelor's degrees. This is perhaps indicative of the rising cost of living in these areas as a college degree indicates greater earning potential. It would be helpful to examine the trends in the impact of student debt on these educated urban dwellers to see if there is a lower debt level amongst this group when compared to the average educated young adult. 47 Housing the Millennial Generation - Trends in the Living Arrangements of Young Adults Bibliography Baum, S.
