who is in charge of drawing congressional district boundaries
Redistricting In 28 states, the state legislature has primary responsibility for creating a redistricting plan, in many cases subject to approval by the state governor. To reduce the role that legislative politics might play, twelve states (Alaska, Arizona, California, Colorado, Hawaii, Idaho, Missouri, Montana, New Jersey, Ohio, Pennsylvania, and Washington) determine congressional redistricting by an independent or bipartisan redistricting commission.[1] Five states: Maine, New York, Rhode Island, Vermont, and Virginia give independent bodies authority to propose redistricting plans, but preserve the role of legislatures to approve them. Arkansas has a commission composed of its governor, attorney general, and secretary of state. Seven states have only a single representative for the entire state because of their low populations; these are Alaska, Delaware, Montana, North Dakota, South Dakota, Vermont, and Wyoming.
Lists of electoral districts by nation In the United States, electoral constituencies for the federal House of Representatives are known as congressional districts (of which there are presently 435; the number can be changed but has remained at 435 since 1912, except for a brief period from 1959-1962 when two seats were temporarily added for the then-new States of Alaska and Hawaii), while the constituencies for the variously named state legislatures go by a variety of names (and have differing numbers). Long standing practice, reinforced and modified by several U.S. Supreme Court decisions, require the equalization of populations of constituencies after each decennial census, a process known as redistricting.
