It is a critical element in the Census Bureau's reengineered 2010 census.
The decennial census has two parts:
1) the short form, which counts the population; and
2) the long form, which obtains demographic, housing, social, and economic information from a 1-in-6 sample of households. Information from the long form is used for the administration of federal programs and the distribution of billions of federal dollars.
Since this is done only once every 10 years, long-form information becomes out of date.
Planners and other data users are reluctant to rely on it for decisions that are expensive and affect the quality of life of thousands of people.
The American Community Survey is a way to provide the data communities need every year instead of once in ten years. It is an on-going survey that the Census Bureau plans will replace the long form in the 2010 Census.
The American Community Survey is conducted under the authority of Title 13, United States Code, Sections 141 and 193.
The Census Bureau may use this information only for statistical purposes. Title 13 requires the Census Bureau to keep all information about respondents strictly confidential.
Any Census Bureau employee who violates these provisions is subject to a fine of up to $250,000 or a prison sentence of up to five years, or both.
Full implementation of the American Community Survey is planned in every county of the United States, pending Congressional funding.
The survey would include three million households. Data are collected by mail and Census Bureau staff follow up with those who do not respond.
The American Community Survey will provide estimates of demographic, housing, social, and economic characteristics every year for all states, as well as for all cities, counties, metropolitan areas, and population groups of 65,000 people or more.
For smaller areas, it will take three to five years to accumulate sufficient sample to produce data for areas as small as census tracts.
For example, areas of 20,000 to 65,000 can use data averaged over three years.
For rural areas and city neighborhoods or population groups of less than 20,000 people, it will take five years to accumulate a sample that is similar to that of the decennial census.
These averages can be updated every year. Eventually, we will be able to measure changes over time for small areas and population groups.

Ignore the mailed literature, and refuse to entertain the "Census Bureau staff follow up".
