This is a special tabulation of data providing data on the citizen voting age population and other data from the 2008_2012 5-year American Community Survey (ACS). The ACS is the replacement for the decennial census long form. This is the fourth release of this special tabulation of ACS data. The first used the 2005-2009 5-year ACS data, the second used the 2006-2010 5-year ACS data, and the third used the 2007-2011 5-year ACS data. Data from all four releases are available on the Census Bureau's Redistricting Office web site, https://www.census.gov/rdo. The data in this tabulation were collected in the American Community Survey between 2009 and 2013. The American Community Survey is an ongoing survey that provides data every year -- giving communities the current information they need to plan investments and services. Information from the survey generates data that help determine how more than $400 billion in federal and state funds are distributed each year. To help communities, state governments, and federal programs, we ask about a variety of topics, including age, race, ethnicity, and citizenship. For more information on the American Community Survey, go to https://www.census.gov/acs.

The data are available in two formats: in SAS data sets or in CSV (comma-separated values) format. SAS is a statistical analysis software package, and CSV files can be read into a large number of software programs such as Excel or Access. Note that in the CSV files, the variable name is the first row in the file. The files are named the same and are in the same format as they were in the 2006-2010 5-Year and 2007-2011 5-Year CVAP releases.

There are seven tables in this data release, grouped by geographic summary level. The file names are:

• Nation (summary level 010)
• State (summary level 040)
• County (summary level 050, based on boundaries as of January 1, 2012)
• Place (summary level 160, based on boundaries as of January 1, 2012)
• MCD (Minor Civil Division, summary level 060, for the 12 strong MCD states: CT, ME, MA, NH, RI, VT, MI, WI, NJ, NY, MN, and PA, based on boundaries as of January 1, 2012)
• Tract (summary level 140, note that these are 2010 Census tracts)
• BlockGr (summary level 150, note that these are 2010 Census block groups)

Each file contains the following variables:

• GEONAME: The name of the geographic area, like "United States", "New Hampshire", or "Houghton County, Michigan"
• LNTITLE: The description of the line, such as "Not Hispanic or Latino" or "Asian and White". Note that the race groups under "Not Hispanic or Latino" only include people who are not Hispanic or Latino, so "Asian and White" includes non-Hispanic Asians and Whites.
• GEOID: This is the identification number of the geographic area for this line:
  
  

  File	GEOID format
  Nation	01000US
  State	04000USss, where ss = two-digit state FIPS code
  County	05000USssccc, where ss = two-digit state FIPS code and ccc = three-digit county FIPS code
  Place	16000USssppppp, where ss = two-digit state FIPS code and ppppp = five-digit place FIPS code
  MCD	06000USsscccmmmmm, where ss = two-digit state FIPS code, ccc = three-digit county FIPS code, and mmmmm = five-digit MCD FIPS code. Note that while it is rare, an MCD can be in two counties in a state.To get the whole MCD, you must add together the parts of the MCD that are in each county.
  Tract	14000USssccctttttt, where ss = two-digit state FIPS code, ccc = three-digit county FIPS code, and tttttt = sixdigit tract code
  BlockGr	15000USsscccttttttb, where ss = two-digit state FIPS code, ccc = three-digit county FIPS code, tttttt = sixdigit tract group code, and b = one-digit block group code
