Montgomery
County Planning Area Profiles from the 2003 Census Update
Survey - Introduction
The
following profiles present key demographic data from the 2003
Census Update Survey describing planning areas in Montgomery
County, Maryland. Survey data are reported for four housing
structure types: single-family detached, townhouse, garden
apartment, and high-rise apartment in each planning area where
they exist. Groups of rural planning areas around Damascus
and Poolesville are combined to yield adequate survey results
for reliable estimates. A schematic map outlining the planning
area boundaries is included.
The
tables for each area and the County detail population, employment,
housing, and income data collected in the summer of 2003.
At the top of each profile is the estimated land area in square
miles for each planning area*. The population sections include:
estimated residential population, age distribution, race,
Hispanic origin, educational attainment, employment, and commuting
data. The household data cover: structure type, tenure, mobility,
household type, household size, income, and housing costs.
Definitions of the data items listed in the tables are found
in "Definition
of Data Items (pdf)*".
The
2003 Planning Area profiles have been expanded from earlier
profiles to include additional data items and increased detail
within categories. It should be noted that data describing
some small subpopulations are not reported in instances where
there are insufficient survey returns for a reliable estimate.
For such occurrences, suppressed data items are reported as
asterisks within the tables. For example, in a planning area
with a low percentage of women with children under age 6 there
may be very few returned surveys answering the question whether
the mother is employed. Usually, responses from at least ten
households are needed for reporting survey results.
The
population and housing data reported in the tables are compiled
from the 2003 Census Update Survey conducted by the Montgomery
County Planning Board. The Census Update Survey updates the
decennial U.S. Census figures and measures the demographic
changes occurring during the decade. The 2003 Census Update
Survey is the eighth in a historical series of household surveys
conducted since 1974. During the summer of 2003, approximately
16,000 survey forms were mailed to a stratified, random sample
of Montgomery County households. About 63 percent of the sampled
households returned the form.
