1913–1933: 36 seats

Following the 1910 census, the delegation grew by four seats to its largest size to date. The four new seats were elected at-large statewide. Starting in 1923, however, four new districts were added to replace the at-large seats.
The results of the 1920 census revealed a major and continuing shift of the population of the U.S. from rural to urban areas. However, no apportionment was carried out following the 1920 census^[3]
