Tract-to-Tract Comparability File

Comparability Files are intended to generate comparable estimates of selected demographic, socio-economic, and housing variables across decennial censuses. Due to changes in population and street patterns, some census tract boundaries are adjusted with each census. Comparability files are the only source of census data that normalize changes in tract boundaries from one census to the next. The State Data Center (SDC) has prepared two separate comparability files:

• The 1970–2000 file provides an analysis of changes that took place across the 1970, 1980, 1990, and 2000 censuses; a total of 27 variables are included and all variables are normalized to 1990 census tract boundaries. This file is available at no charge.
