University of Massachusetts Donahue Institute Population Estimates Program For Release March 19, 2009 U.S. Census Releases County-level Population Estimates for 2000 to 2008 The U.S. Census Bureau released July 1st county-level population estimates for 2000 to 2008 for Massachusetts and the U.S. on March 19, 2009. These estimates are based on the demographic “components of change”, which include births and deaths, internal and international migration, and the group quarters population for each county. To go directly to the U.S. Census estimates page, follow this link: http://www.census.gov/popest/counties/ State Total Overview State-level estimates for Massachusetts released by the U.S. Census Bureau in December of 2008 increased the state population by 30,052 persons, or 0.46% over the previous year, to 6,497,967 persons. This marked the third year of consecutive increases in the Massachusetts population estimates after the state showed losses in 2004 and 2005. Massachusetts has lagged behind U.S. population growth since the 2000 Census, however this last vintage release shows that the percentage gap has been steadily decreasing since 2004. For more details on the state level estimates, including a comparison to both the Northeast Region and the U.S., components of change, and comparison of vintages, please refer to our December 23, 2008 release: UMass Donahue Institute Summary of U.S. Census Bureau’s 2008 Population Estimates at http://www.massbenchmarks.org/statedata/news.htm County Totals The greatest numerical increases from 2007 to 2008 were found in: Middlesex County 12,680; Suffolk County 5,138; and Norfolk County 4,551. The greatest numerical decreases were in: Barnstable County -941; Berkshire County -637. All other counties showed some net gain. In terms of percentage of change, the largest gains were in: Nantucket County at 1.4%; Middlesex at 0.86%; and Suffolk at 0.71%. Nantucket County’s population increased dramatically as the result of a successful challenge to its 2007 estimates. The Suffolk County increase is the result of an increased Group Quarters population, also resulting from a challenge process. These three counties had the three highest “natural increases” from 2007 to 2008, meaning they had high numbers of births compared to deaths, and they also had the three highest percentages of international migration boosting their population estimates. The largest decreases were in: Berkshire County at -0.49%; and Barnstable County at -0.42%, both of which counted more deaths than births in 2008. All other counties showed gains of less than 1%. The following three tables show the 2008 vintage time series of Massachusetts countylevel estimates for 2000-2008, including population estimates by county and by year, numeric change from year to year and cumulative from the 2000 estimates base, percentage changes, and rankings. Note that the estimates for 2000 to 2008 shown below incorporate the latest information available to the U.S. Census Bureau, and differ from the previous “vintage” estimates produced for those years.

The following section describes changes in the Massachusetts county-level population estimates within these individual components, and compares these components at a county level. Natural Increase Natural increase is the net increase after births and deaths are added together. The following chart shows, for each county, the number of births, deaths, and the resulting natural net increase for 2008. 2008 Births, Deaths, and Net Natural Increase by County BIRTHS DEATHS Net Natural Increase 20000 15000 10000 5000 Worcester County Suffolk County Plymouth County Norfolk County Nantucket County Middlesex County Hampshire County Franklin County Essex County Dukes County Hampden County -15000 Bristol County -10000 Berkshire County -5000 Barnstable County 0 The following Tables 4, 5, and 6 show the actual numbers of births and deaths by county and by year as well as the resulting net natural increase. A column in each table shows the 2008 component as a percentage of the estimated 2008 population for that county, and the last column ranks the counties by these percentages. Counties are sorted in each table by rank number.

Release Date: March 19, 2009. Migration In the estimates process, the migration component refers to the number of people moving in and out of a county. International migration measures the number moving to or from places outside of the U.S. These numbers are estimates produced by the U.S. Census Bureau by looking at records from the Department of Homeland Security and other sources. Internal migration, sometimes called domestic migration, measures movement from one county to another within the United States. The sum of these two types of migration equals the net migration. The following chart shows, for each Massachusetts county, the international, internal, and net migration for 2008. 2008 International, Internal, and Net Migration INTERNATIONAL INTERNAL Net Migration 8000 6000 4000 2000 -6000 -8000 Worcester County Suffolk County Plymouth County Norfolk County Nantucket County Middlesex County Hampshire County Hampden County Essex County Dukes County Bristol County Franklin County -4000 Berkshire County -2000 Barnstable County 0 The following Tables 7, 8, and 9 show the international, internal, and net migration totals by county and by year. A column in each table shows the 2008 component as a percentage of the estimated 2008 population for that county, and the last column ranks the counties by these percentages. Counties are sorted in each table by rank number.

In 2007, Massachusetts updated its GQ population counts with the U.S. Census Bureau for the first time since 2002. This new data provided the basis for successful population challenges in 16 Massachusetts municipalities, which resulted in the upward revision of their official 2007 population estimates. For a complete list of challenge results, follow the link below to the U.S. Census’ Estimates Division page: http://www.census.gov/popest/archives/2000s/vintage_2007/07s_challenges.html Because these challenges revised the previous vintage’s group quarters population counts, the following table compares the 2007 vintage (version) of the 2007 GQ component in Massachusetts counties to the 2008 vintage of the 2008 GQ component.
