Geolytics Neighborhood Change Database This link opens in a new window
The Geolytics Neighborhood Change Database (NCDB) gives users access to US Census data from 1970, 1980, 1990, 2000, and 2010 at the census tract level, with the option to access data for all four decades normalized to 2010 tract boundaries. Users can download data as if the 2010 tracts existed, and all the data is weighted to these areas. Variables include population, household, and housing characteristics, income, poverty status, education level, employment, housing costs, immigration, and others. Users can export data in .dbf, ASCII, shapefile, or mid/mif files.
