Built in the 1920s
Warren Harding took office in 1921, Calvin Coolidge succeeded him in 1923 and Herbert Hoover was elected in 1928. The census of 1920 was the first to count more Americans in towns and cities than on farms. Prohibition was in force and the automobile and the radio spread quickly. The stock market crashed in October 1929.
2,415 places on the National Register have a construction year in the 1920s on record. They stand in 53 states and territories. Of those, 52 are National Historic Landmarks.
Construction years come from Wikidata, matched on National Register reference number. Only plain four-digit years are counted, so a place recorded as circa or as a range is left out. Data refreshed November 02, 2026.
