US Census Longitudinal data

The data file contains multiple variables at the census tract level (using 2010 tract boundaries) for the years 1980, 1990, 2000, 2010, and 2019. Note that the 1970 data is not compailed because the 1970 decennial census does not have a question about ethnicity. Another caveat is that the US was fully tracted from 1990 census, which means that many tracts do not have data in the year 1980.
