Бюро переписи населения США регулярно публикует геобазу данных TIGER. Этот набор данных содержит группы участков переписи 2020 года, представляющие собой кластеры участков в пределах одного переписного участка, имеющих одинаковую первую цифру четырёхзначного номера участка переписи. Всего имеется чуть более 240 000 полигональных объектов, охватывающих территорию США, округа Колумбия, Пуэрто-Рико и острова.
