The 2010 Census Tract Relationship files are provided as a tool to help data users compare the universe of Census 2000 tracts to the universe of 2010 Census tracts. From these files, data users may determine how Census 2000 tracts relate to 2010 Census tracts and vice versa. The links below provide more information about the relationship files, including format and layouts, as well as a link to the downloadable files.

Note: These files DO NOT include population data. At a later date, we will put out another set of files with population data.
