Corrections to Published Census Counts

The Census Bureau’s goal is to count everyone once, only once, and in the right place.  Historically, in a small percentage of cases, incorrect geographic boundary or coding of a housing unit or group quarters were used to produce the official census counts for a local area.  When discovered, the Census Bureau will publish corrections to the total population and total housing units counts. While these corrections change the official 2010 census population for the affected jurisdictions, the data files and online products produced by the Census Bureau will not reflect these revisions.

2000-2010 Tract-To-Tract Comparability Files

Comparability files are intended to generate comparable estimates of selected demographic, socio-economic, and housing variables across decennial censuses. Due to changes in population and street patterns, some census tract boundaries are adjusted with each census. Comparability files are the only source of census data that normalize changes in tract boundaries from one census to the next. The State Census Data Center (SCDC) has posted three comparability files:

The 2000–2010 files include a total of 176 variables from the 2000 and 2010 censuses and 2006-2010 (5-year estimates) American Community Survey with all variables normalized to 2010 census tract boundaries.
