Geography Notes for Current Release

Census Tract and Block Group changes in New York State

For the 2011 ACS data release, there are tract numbering corrections and minor geographic definition changes to census tracts in Madison, Oneida and Richmond counties, New York. The census tract changes in Madison and Oneida Counties are the result of corrections to the Oneida American Indian Reservation boundary after the 2010 Census tract definitions had been finalized. The change to the census tracts in Richmond County corrects a tract boundary definition error.
