Das US Census Bureau veröffentlicht regelmäßig eine Geodatabase namens TIGER. Dieses Dataset enthält die Blockgruppen der Volkszählung von 2020. Eine Blockgruppe ist eine Gruppe von Blöcken innerhalb desselben Erhebungsgebiets, die dieselbe erste Ziffer ihrer vierstelligen Erhebungsblocknummer haben. Es gibt etwas mehr als 240.000 Polygon-Features, die die USA, den District of Columbia, Puerto Rico und die Inselgebiete abdecken.
