Final population figures from the 1960 Census of Population for the 426 congressional districts in the United States, as defined on April 1, 1960. Although the House of Representatives currently has 437 members, 11 are elected at large and do not represent specific congressional districts.

Representatives are elected at large in the six States that currently have one Representative (Alaska, Delaware, Hawaii, Nevada, Vermont, and Wyoming). In addition, New Mexico and North Dakota elect both of their Representatives at large and Connecticut elects one of its six Representatives at large.

The data shown in this report relate to the congressional districts that were established in accordance with an apportionment based on the results of the 1950 Census. This apportionment allocated 435 Representatives to the 48 States then in existence.

Membership in the House of Representatives was increased temporarily to 437 with the admission of Alaska and Hawaii as States. In November 1960, the Bureau of the Census submitted an apportionment based on the final results of the 1960 Census. In accordance with existing law, House membership would revert to 435. Because of changes in their number of Representatives, many States will revise their districts. The Bureau of the Census will publish the population of the districts established for the elections of November 1962 later.
