TIGER2021 Census Tract Shapefiles vs. FFIEC.gov Census Flat File

Hi All,

I'm glad I found this forum, have a question for a current project that I'm working on.

A discrepancy in the total number of Census Tracts comparing:

This analysis only includes Census Tracts within the 50 states and DC.

For the 50 states + DC, there are:

  • 84414 Census Tracts in the TIGER2021 Shapefiles.
  • 74771 Census Tracts in the FFIEC.gov 2021 Census Flat File.
  • These two sources only have 61638 Census Tracts in common for the 50 states + DC.

Objectives:

  1. Retrieve the Census Flat File columns for all the unmatched Census Tracts in the TIGER2021 Shapefiles.
  2. Retrieve the Shapefiles for all the unmatched Census Tracts in the FFIEC.gov 2021 Census Flat File.

Thanks,

CJ

  • Also, you might like to try using IPUMS NHGIS, which provides census tract shapefiles based on TIGER/Line files, but in nationwide files (rather than split up by state), clipped at the coastlines and projected into an Albers equal area conic projection, suitable for nationwide mapping and analysis.

    Or for census tract population centers (which are more suitable for many types of spatial analysis than the shapefile centroids), see this Census web page.
