Le Bureau du recensement des États-Unis publie régulièrement une géodatabase nommée TIGER. Ce tableau contient les valeurs du profil démographique 1 du recensement de 2010, agrégées par secteur de recensement. Les zones de recensement varient énormément, mais dans les zones urbaines, elles sont à peu près équivalentes à un quartier. Il existe environ 74 000 entités polygonales couvrant les États-Unis, le District de Columbia, Porto Rico et les zones insulaires.
Chaque zone comprend également des attributs avec les sommes des mesures de population DP1 qui croisent la limite. Les colonnes portent le même nom que la colonne "shortname" (nom abrégé) dans la table de recherche DP1.
