6 Decades (1970-2020) of Tract Data in 1 Product - Neighborhood Change Database (NCDB)

The Neighborhood Change Database (NCDB) 2020 has Tract level
data from 1970, 1980, 1990, 2000, 2010 and now 2020. In
addition to having the data in the year-specific boundaries it
also has them all normalized to the 2020 tract boundaries.
This means that you can easily explore changes in U.S. demographics
from 1970 to 2020 all in the same geographic boundary definitions.

We have worked hard to create a cohesive set of variables over the
60 years - they have the same codes so you know you are looking at
the same variable definitions. And now they are sorted by Groupings
so it is easy to find the information you are looking for. Each of the variables is now sorted into one of the Groupings: Population;
Age ? Sex; Race; Journey to Work; Households ? Families; Education; Language; Poverty; Income; Employment and Housing.
Within each of these Groupings there can be multiple Categories/Tables. For example, in the Grouping Income there are 8 Categories:

Family Income, Families by Income, Per Capita income, Earnings, Household Income, Households by Income, and Median Household income. Within
each of these Tables there can be many variables. These categories
make it much easier to find the variables you are looking across the multiple decades than the previous versions of our NCDB.

Characteristics (DHC) 2020 and the American Community Survey (ACS)

dbf or csv file to easily use in a database or statistical
software package.
