GeoLytics News: Neighborhood Change Database (NCDB) 2010 Now Available from GeoLytics

Neighborhood Change Database (NCDB) 2010 Now Available from GeoLytics

The Neighborhood Change Database 2010 has Census Tract data from 1970, 1980, 1990, 2000, and 2010.  In addition to having the data in the year-specific boundaries it also has them all normalized to the 2010 tract boundaries.  This means that you can easily explore changes in U.S. demographics from 1970 to 2010 all in the same geographic boundary definitions.  The power of this database comes from cross-walking the 1970, 1980, 1990, and 2000 census data to 2010 census tract boundaries, meaning that you can do a real apples-to-apples comparison for the data without having to make accommodations for the changing boundaries – we’ve already done that for you. 

With the Neighborhood Change Database researchers can examine population transformations in urban communities over 50 years.  With GeoLytics’ proprietary block weighting algorithms, you get accurate calculations for comparing census tract data from the 1970 through 2010 census in a uniform set of boundaries.  For more information go to:

For added flexibility we have also included the 1970-80-90-2000 data in their year specific tract boundaries.

GeoLytics and the Urban Institute developed the Neighborhood Change Database, with partial funding by the Rockefeller Foundation.  It combines tract level data from the 1970 through 2010 decennial censuses.  The NCDB 2010 has 2010 data from both the Summary File 1 (SF1) and the American Community Survey (ACS) databases. 
There are 568 variables from the SF1 and an additional 1,625 from the 2006-2010 ACS data file.  Similarly there are 1,800 variables from the 2000 Census Long Form (SF3), 1,100 variables from the 1990 Long Form, 1,100 variables from the 1980 Long Form, and
800 variables from the 1970 Long Form.  For a complete list of variables go to:

Like all of our Census products, the Neighborhood Change Database has functional mapping capabilities and easily exports geographic tract boundaries.  You can also export the data as a dbf or csv file to easily use in a database or statistical software package.
