|Abstract:||These are the normalized tract data files used by the Longitudinal Tract Database to update the tract boundaries. These data files consists of selected "long-form" census tract data from 1970, 1980, 1990, 2000 census, and the 2006-2010 ACS, all normalized to 2010 boundaries. If items you want are not available, you can use the interface to input any census-tract based item and normalize it to 2010 boundaries.|
