After the 13th census in 1910 Congress set the size of the House at 435 (effective with the 63rd Congress which commenced in 1913).
Ten years later, after the 14th census in 1920, the members of the House were unable to reach agreement on a reapportionment bill and, for the first time in history, Congress failed to fulfill its constitutional obligation to reapportion the House. Thus the apportionment of the House remained unchanged from 1913 to 1922.
