Longitudinal Tract Database [LTDB]: 1970 to 2010
The LTDB provides estimates using 2010 census tract boundaries for a standard set of variables from 1970 through 2010. Currently, the data only include short-form variables, but the resource also includes a stata program that normalizes any user-provided input to 2010 boundaries.
The data and all files can be downloaded from the source - Brown University. We also have the files on the PSC network as W:\\LTDB.
Neighborhood Change Database [NCDB]: 1970-2000
CensusCD Neighborhood Change Database (NCDB) gives users instant access to US Census data from 1970, 1980, 1990 and 2000 at the census tract level. This product (CD) is accessible through PSC data services.
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 four decades. The NCDB contains 1970, 1980, 1990, and 2000 Long Form data with details such as: population, household, and housing characteristics, income, poverty status, education level, employment, housing costs, immigration, and other variables.
PSC is somewhat unlikely to purchase the 2010 release from Geolytics because researchers can use the LTDB stata program to update any of the NCDB files to 2010 boundaries.
CensusScope is an easy-to-use tool for investigating demographic trends. It is based on tabular data from the Census and American Community Survey. Users can download figures, maps, and rankings based on the data, but in general this site does not allow one to download characteristics for all counties or states.
The strength of this site is that it has produced some of the best summaries based on tabular data. In other words, it simplifies all the 3,255 tables into an understandable concept such as "nuclear families."
USA Counties features over 6,500 data items for the United States, States and counties from a variety of sources. Files include data published for 2008 estimates and many items from the 2000 Census of Population and Housing, the 1990 census, the 1980 census and the 2002, 1997, 1992, 1987, 1982 and 1977 economic censuses.
Information in USA Counties is derived from the following general topics: age, agriculture, ancestry, banking, building permits, business patterns, crime, earnings, education, elections, employment, government, health, households, housing, income, labor force, manufactures, population, poverty, retail trade, social programs, veterans, vital statistics, water use, and wholesale trade.
County and City Data Books
This resource provides access to the 1944 through 2000 County and City Data Books. This service provides the opportunity to create custom printouts and/or customized data subsets.
ICPSR has newer releases of the County and City data book, but in a form that requires programming. A more readily usable source, also from ICPSR is County Characteristics, 2000-2007 [Study 20660]
