Neighborhood Change Database (NCDB)

NCDB allows users to compile census tract data from the Long Form results of the US Censuses for 1970, 1980, 1990, 2000 and 2010.  That data includes  population, household, and housing characteristics, income, poverty status, education level, employment, housing costs, immigration, and other variables.  The database's distinctive feature is the normalization of data to the latest tract boundaries.  Original boundaries can be accessed one census at a time.  It is most useful if users already know their tract numbers. Please note that this database is not networked and requires a staff person to log in, please speak with a staff person for assistance.  **Patrons should read the Terms & Conditions and Privacy Policy of this resource before searching.**
