American Community Survey 2012
  -- 2008-12 5-Year Estimates

There are several things to like about the new American Community Survey 2012 (ACS 2012) 5-year demographic-economic data (available 12/17/13). These data are one year more recent data than released in December 2012 (the ACS 2011 5-year data). As a result, they provide an updated and more current picture. Two, this is a third year sequel to having Census 2010 vintage census tract and block group data available. This de facto three year mini-time series enables a start to examine trends. Three, these estimates are centric to mid-2010 and thus roughly comparable to what would have been "richer demographics" from Census 2010 (had the long-form not been eliminated). This enables a rough comparison between 2000 and 2010 (it will be the best opportunity ever). These data provide unique and powerful measures that facilitate development of decision-making information.

This section is focused on ACS 2012 5-year estimates data access and use, applications using these data and the integration and analysis of these data with other data. Census 2010 and ACS 2012 provide the most current Census-sourced demographics for wide-ranging geography.

API Data Access & Use
Use the CV APIGateway to access ACS 2012 5-year estimates by block group (the low level geographic data availability for these data) and higher level geography. Extracted datasets may be integrated directly with shapefiles for thematic mapping and pattern analysis. The graphic shown below illustrates use of ACS 5-year block group data extracted using the APIGateway and integrated into a block group shapefile, all developed with CV XE GIS.
