Changing Ranks of States by Congressional Representation
August 30, 2012



The number of representatives given to each state as a result of apportionment has shifted over time. Shifts in political representation are due to changes in state population relative to other states, the admission of new states to the union, and increases to the total number of memberships in the U.S. House of Representatives instituted by Congress over the decades. The seven states with the largest number of representatives in a given year are included in the graph, beginning with the Continental Congress in 1789 (prior to the first decennial census) and following each decennial census from 1790 through 2010.
