FAQ

What is the difference between TIGER/Line and census demographic data?

TIGER/Line provides geographic boundary shapefiles (geometry only), while census demographic data provides population and housing statistics. You join demographic tables to TIGER boundaries using GEOID codes.

Can I get TIGER data as GeoJSON?

Yes. While TIGER/Line shapefiles are the primary format, the Census Bureau also provides a WMS/WFS service via TIGERweb and some GeoJSON exports.
