The U.S.
Census Bureau released today
tabulations from the 2004 American Community Survey (ACS).
This annual survey is the largest household survey in the
United States (800,000 housing units per year during its test
phase from 2000 to 2004). |
|
The
American Community Survey is a new nationwide survey designed to
provide communities a fresh look at how they are changing. It will
replace the long form in future censuses and is a critical element
in the U.S. Census Bureau’s reengineered
2010 census plan |
Like the decennial census
long form it is designed to replace, the ACS provides information on
money income and poverty, as well as a wide
range of other social,
economic, and housing indicators
for the population living in
households. From the 2004 ACS, these
demographic estimates have been produced for
the United States, all 50 states, and essentially
all places, counties, and metropolitan areas with at least 250,000
people.
In Northeastern Illinois,
that includes data for the city of Chicago and each of the six counties
(Cook, DuPage, Kane, Lake, McHenry, and Will) that comprise Northeastern
Illinois. Information is also presented for a nine-county
metropolitan area aggregate (the six counties mentioned previously plus
DeKalb, Grundy, and Kendall).
Two types of 2004 ACS profiles are
available for each geography - data tables (Excel format) and narrative
text accompanied by charts (PDF format):
To generate 2004 ACS data and narrative profiles
that can be printed and downloaded for any large geographic area in the
U.S., please go to:

At
http://www.census.gov/acs/www/Products/index.htm,
a data user can, for the
available geographies, also access side-by-side comparisons of annual ACS
results from 2000 to 2004.
Starting in 2006, the Census Bureau expects
data will be available for all areas with populations of 65,000 or more.
And by 2010, data will be available down to the census tract and block
group levels.
Please note that the
2004 American Community Survey universe is limited to the household
population and excludes the population living in institutions, college
dormitories, and other group quarters. Data are based on a sample and
are subject to sampling variability. The degree of uncertainty for an
estimate is represented through the use of a confidence interval. The
confidence interval computed here is a 90 percent confidence interval
and can be interpreted roughly as providing 90 percent certainty that
the true number falls between the lower and upper bounds.
