Census Tract Crosswalks

a PSC Data Resource

Resource Source:ICPSR & Census Bureau


These are files that show the crosswalk from one census to the other for census tracts. There are files for 1970 to 1980; 1980 to 1990; 1990 to 2000; and 2000 to 2010.


Other sources for this are the Neighborhood Change Database and the Longitudinal Tract Database. In both of these cases, the data are normalized to the most recent year and across multiple decades instead of decade to decade.
