Size of the U.S. House of Representatives



November 30, 2020
The size of the U.S. House of Representatives is set by federal statute at 435 Representatives (excluding
nonvoting seats held by Delegates and the Resident Commissioner). This number has been constant since
the start of the 63rd Congress in 1913, aside from a temporary increase to 437 seats to accommodate the
additions of Alaska and Hawaii as states in 1959 (see P.L. 85-508, July 7, 1958; P.L. 86-3, March 18,
1959) until the apportionment that followed the 1960 census.


Requirements Affecting House Size

Article I, Section 2 of the U.S. Constitution, as amended by Section 2 of the 14' Amendment, provides
that representation in the House is based on state population size. In order to determine the population of
each state, Article I, Section 2 requires that the national population be counted at least once every 10 years
through what is known as the decennial census. Article I, Section 2 also contains broad parameters for
House size, stating that there can be no more than one Representative for every 30,000 persons, provided
that each state receives at least one Representative. Within these constitutional parameters, the House
could in theory be as small as 50 Representatives or as large as about 10,000 Representatives, based on
the 2010 census apportionment population. The number of House seats to be apportioned across states is
set by 2 U.S.C. §2a.


Historical House Size

Figure 1 displays the number of House seats and the U.S. population over time, along with the average
district population size nationwide (or representation ratio). In the 18t and 19t centuries, Congress
generally increased the size of the House with each apportionment so no state would lose seats. The only
exception followed the 1840 census, when Congress decreased the number of seats from 242 to 232. The
1911 apportionment act set the House size at 433 and allowed for the addition of one seat each to
accommodate  the anticipated statehoods of Arizona and New Mexico. The Permanent Apportionment Act
of 1929 established that seats would be apportioned based on the then existing number of
Representatives, which was 435, beginning with the 1930 census. This language from the 1929 act
remains at 2 U.S.C. §2a.
