City-generated population estimates and projections
The planning Department generates monthly population estimates and future population projections based on recent development activity.  These estimates are adjusted every ten years as decennial Census figures are released.

The City’s Economic Development partnership with the Chamber of Commerce compiles additional demographic information from a variety of sources.

    Census   
    2010 Census  data for Texas was released in February 2011. The Census is a population count of everyone in the US taken every ten years. Decennial Census data are used to allocate states’ congressional seats, to make decisions about what community services to provide, and to distribute more than $300 billion in federal funds to local, state and tribal governments each year.

    1 This Metropolitan Statistical area is now named the "Austin-Round Rock MSA," although in earlier decennial Censuses it was referred to as the "Austin-San Marcos MSA."
    2 The Austin-San Marcos MSA in 1990 and 1980 was defined as Travis, Williamson and Hays Counties; populations of Bastrop and Caldwell Counties have been added so that the MSA geographies match later Censuses.

    American Community Survey 
    The US Census Bureau also collects a wealth of demographic information annually through the American Community Survey (ACS).  Surveys are sent to only a sampling of households, so ACS data are estimates, not 100% counts.  This allows responses to be processed and reported much more quickly than the decennial Census.  Survey data is also grouped into 3-year and 5-year estimates – these multi-year estimates are generally more accurate because of the combined sample size, but less current than the 1-year estimates.

    Economic Census and Survey   
    The Bureau also collects the Economic Census  every five years (those ending in '02 and '07), and an annual Economic Survey.  The economic census provides a detailed portrait of the United States' economy once every five years, from the national to the local level. There also are several related programs, including statistics on minority- and women-owned businesses. Censuses of agriculture and governments are conducted at the same time.
