American Community Survey (ACS)

Data Releases Dates

Starting with the data collected in 2005, ACS information has been published for areas with population 65,000 or more. In the fall of 2008, the first 3-year estimates were released based on data from the 2005, 2006 and 2007 surveys for geographic areas with populations of 20,000 or more. By 2010, the Census Bureau plans to provide the first 5-year estimates of demographic, housing, social and economic data for geographic areas down to the block group level. These 5-year estimates will then be updated annually by removing the earliest year and replacing it with the latest one. This will provide, for the first time, the ability to monitor social and economic trends in local communities.

Note: On the following table, the columns represent the calendar year (CY) when data are released and the rows represent the year (or years) of data collection.

* Five-year estimates will be available for areas as small as census tracts and block groups.
