Why don't I see an American Community Survey (ACS) Selected Population Profile (SPP) table for a specific group in my city or county?

There are two thresholds used for Selected Population Profiles (SPPs).

First, we look at the total population size of the geographic area. Beginning with the 2007 American Community Survey (ACS), SPPs are released for geographic areas with a total population of at least 500,000. Prior to the 2007 ACS, SPPs were produced for geographic areas with a total population of at least 1 million.

Second, we look at the size of the population group of interest. 

  • The 1-year SPPs are released for population groups with an estimated population of 65,000 or more. 
  • The 3-year SPPs are no longer produced*, but are available for 2011-2014 and earlier for population groups with an estimated population of 20,000 or more. 
  • The 5-year ACS estimates do not include SPPs. However, a product similar to Census 2000 Summary File 4 and the American Indian and Alaskan Native Summary File was released in 2012 using 2006-2010 ACS 5-year estimates.   Learn more about this special data release.

SPPs provide summary tables separately for over 100 detailed race, ethnic, ancestry, and tribal groups. Beginning with the 2007 American Community Survey, the SPPs are also available for approximately 100 countries and region of birth groups.

You can also visit the Data Suppression page to learn more bout why certain estimates are not available.

*ACS 3-year estimates have been discontinued. The 2005-2007, 2006-2008, 2007-2009, 2008-2010, 2009-2011, 2010-2012 and 2011-2013 ACS 3-yer estimates will remain available to data users, but no new 3-year estimates will be produced. Every community in the nation will continue to receive a detailed statistical portrait of its social, economic, housing, and demographic characteristics through the 1-year and 5-year ACS products.
