Le Bureau du recensement des États-Unis publie régulièrement une géodatabase nommée TIGER. Cet ensemble de données contient les secteurs de recensement de 2020. Les zones de recensement varient énormément, mais dans les zones urbaines, elles sont à peu près équivalentes à un quartier. Il existe un peu plus de 85 000 entités polygonales couvrant les États-Unis, le District de Columbia, Porto Rico et les zones insulaires.
