This is a complete 'list of congressional districts' for representation in the
United States House of Representatives. The quantity and boundaries of districts are determined after each
census, although in some cases states have changed the boundaries more than once per census. This list includes the '435 current' and '173
obsolete' districts. For example, since the
2000 census,
Nebraska has had three districts, but it used to have as many as six. Also included here are non-voting delegations: 5 current and 4 obsolete.
The boundaries of districts shift with each
redistricting. Over time, the region and
demographics represented in a district can change substantially. Furthermore, districts sometimes retain the same boundaries while changing their district numbers.
