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.
