 City-generated estimates | Census 2010
Ameican Community Survey | Census Links 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.

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.

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. Census Bureau links
