I. Introduction to the Broward County 2014 TAZ
and Municipal Forecasts Update

An update of forecast model developed in 2012 that was
professionally acceptable and replicable.

A continuation and update of the County’s 2012 TAZ and Municipal
Forecasts.

The update includes modifications and comments obtained from
the 2012 Population Roundtable process approved methodology.

Replaced internally-developed countywide forecasts with
population forecasts prepared by University of Florida’s BEBR.
I. Introduction to the Broward County 2014 TAZ and
Municipal Forecasts Update
Key Input

University of Florida’s BEBR, “Detailed Population Projections by Age, Sex, Race, and
Hispanic Origin, for Florida and Its Counties, 2015-2040, With Estimates for 2012 All
Races”
Key Action

Convert and assign the BEBR forecasted estimates (2015-2040) to Broward County’s 2010
TAZ and municipalities using a household based model.
Key Output

Forecasts of households, household size, group quarters’ population, seasonally-occupied
housing units, and all-other vacant units for years 2015 through 2040 in 5-year increments
and supporting documentation.

TAZ and municipal level forecasts of housing and population data for years 2015 through
2040 in 5-year increments.
** Base year of 2010 provided for reference purposes.
I. Introduction to the Broward County 2014 TAZ and
Municipal Forecasts Update
Household-Based Model Assumptions

BEBR’s forecasts by population age are converted to countywide
household forecasts. Assigned to TAZ based on interaction
between
1. The change in the countywide household-size distribution
through forecast periods;
2. The established TAZ-level distribution of households; and
3. The capacity of each TAZ to absorb additional housing units.
Generally based on the Land Use Plan and vacant land
capacity.
II. BEBR Population Forecast




BEBR annually projects population for Florida and its counties.
The percentage change between 2012 and 2040 is approximately
14.8%.
County population growth is projected to average 10,000 annually
through 2025 and 8,800 for the remainder of the period.
Growth is dramatically lower than County’s historic growth which
averaged 20,000 or more annually between 1970 and 2005.

Most of the future growth will continue to occur primarily in the
most populous counties.
Through 2040, Miami-Dade and Broward Counties remain 1st and
2nd.

Much of Florida’s population growth (25% or nearly 1.7 million
additional people by 2040) will be seen in a swath crossing the
middle portion of the Florida Peninsula, including Orange,
Hillsborough, Polk, Pasco and Osceola Counties.
II. BEBR Population Forecast
Reflections on Recent History
 Past growth was accommodated by the County’s supply of ample
vacant developable land.
 By 2005, nearly all the vacant developable land in the County
was built out.
 Future growth now is primarily dependent on redevelopment.


Total “School Age” population remains relatively stable.

“New Householders” generally increases over the forecast, though there are a
couple of periods of stagnation or even slight declines.

“Peak Earners” cohort trends downward as the workforce is eroded through
life events (retirement)

By 2040, the baby-boom cohort is decreased by more than half of its 2012
size.
III. BEBR Forecast by Age for Broward County
Impacts from within the
age cohorts

Baby-Boomer households downsizing
will compete against new household
creation and have impacts on the
need for health care services, placing
increasing demands on Medicare and
Medicaid while reducing the number
of wage-earners and associated tax
revenues.

While the population gradually
increases, the number of people
generally considered as potential
participants in the labor force remains
constant through 2025 and declines
thereafter.

Relatively fewer dollars circulating in
the economy.

IV. Broward County Households by Age of Householder
Inside the County’s Householders by Age Forecast

Most rapid household increases
occur during the current five-year
period.

As the baby-boomer household
numbers decline from their peak,
there may be an oversupply of
larger family homes awaiting
occupancy.

Doubling of the 65 and older
households while the 45 to 64 age
group gradually declines.

Forecasts portend housing unit
growth at a more subdued pace
than County experienced during
nearly the entire last half century.

baby-boom generation will impact Broward’s housing
market. Whether decide to live in their current homes with extra rooms or
to “downsize” to smaller homes.

If enough downsize, there will be a significant demand for smaller homes
and an excess of larger homes.

If fewer households downsize, the impact likely would be to encourage
redevelopment in more selective areas.

 Presents household size table from a different perspective, the population
according to household size.
 While smaller households occupy the majority of housing units; more of the
population resides in mid-size households (3-, 4-, or 5-person households),
through 2020 slightly more than 50% and slightly less thereafter.
**Note: Household Population = the number of 1-person households + (2 * the number of 2-person
households) + (3 * the number of 3-person households) +…+ (7.83, average size of the 7+ households*
the number of 7+ households)
VI. Assignment of Dwelling Units, Households
and Household Population to TAZs

This stage of allocation occurs into the Broward County’s 2010 TAZ boundaries (953 unique
geographic areas).

Distributed to TAZs by a methodology that respects the individual TAZ’s unique set of
selected characteristics and its capacity to accept growth.

Allocation requires that each TAZ be assigned a maximum number of dwelling units. This
maximum reflects the influence of the Broward County Land Use Plan (amendments and
current designations) and vacant land capacity.

Served as the stage in the 2012 forecasts for the input from the 2012 Population
Roundtable process. Input included:
1.
2.
Estimated maximums for TAZs that contain Regional Activity Centers, Local Activity
Centers, Transportation Oriented Corridors or other irregular Land Use Plan
designations; and
Identification of TAZs for “redevelopment” since vacant residential lands are
exhausted by 2025.
VI. Assignment of Dwelling Units, Households
and Household Population to TAZs
Assignment methodology for TAZs
Step 1.
Determine #of households by size & vacant units required by
next forecast year: Convert existing household size distribution for
each TAZ to reflect anticipated countywide change distribution for
coming forecast year.
Step 2.
Determine attractiveness of each TAZ to accept growth: Vacant
Step 3.
Determine household size distribution of the additional units for
each TAZ: Based on unique distribution of household characteristics,
land capacity, land use plan and its existing housing inventory.
businesses in area, and nearby public services.
Step 4.
Determine preliminary total of households by size assigned to
each TAZ: Matrix of percentages of future growth by household size for
each TAZ.
Step 5.
Enforce TAZ unit maximums: TAZs exceeding maximum have excess
units apportioned by household size; subtracted from the TAZ; and
added into pool of households to be re-distributed.
VII. Municipal Forecast of Dwelling Units,
Households, and Population

Arranging the TAZ forecast data into its proper jurisdiction and
compiling the numbers creates the municipal forecast.
Methodology for assigning TAZs to jurisdictions
Step 1.
Assign TAZs to local jurisdictions: 2012 municipal boundary map
Step 2.
Apportion TAZs among multiple jurisdictions: 2010 Census Block
Step 3.
Benchmark the TAZ assignments to the 2010 Census: Review
Step 4.
Assign Group Quarters Population: Census 2010 rate of 0.97%
