Neighborhood Change Database (NCDB) gives users instant access to US Census data from 1970, 1980, 1990, 2000, and 2010 at the census tract level. This easy-to-use product was developed in association with The Urban Institute and partially funded by The Rockefeller Foundation. It is an invaluable resource for policy makers, community organizations, and researchers who want to analyze changes that have occurred in US neighborhoods over five decades.
