Das US Census Bureau veröffentlicht regelmäßig eine Geodatabase namens TIGER. Diese Tabelle enthält die Werte des Demographic Profile 1 aus der Volkszählung von 2010, die nach Zählbezirk zusammengefasst wurden. Die Größe von Zählbezirken variiert stark, entspricht in städtischen Gebieten aber in etwa einem Stadtteil. Es gibt etwa 74.000 Polygon-Features, die die USA, den District of Columbia, Puerto Rico und die Inselgebiete abdecken.
Jeder Zählbezirk enthält auch Attribute mit Summen der DP1-Bevölkerungsmessungen, die die Grenze überschneiden. Die Spalten haben denselben Namen wie die Spalte „Kurzname“ in der DP1-Nachschlagetabelle.
