Das US Census Bureau veröffentlicht regelmäßig eine Geodatabase namens TIGER. Dieses Dataset enthält die Blöcke der Volkszählung von 2020, die in etwa einem Stadtblock entsprechen. Es gibt etwas mehr als acht Millionen Polygon-Features, die die USA, den District of Columbia, Puerto Rico und die Inselgebiete abdecken.
