how many electoral districts are there in the us
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.
