资源简介:
Congressional Districts depicts the physical extent and demographic profile of each district of the U.S. Congress. The dataset includes population estimates, contact information, and party affiliation for each current congressional representative at the time, along with previous congressional districts for historical comparison.
A Congressional district is a division of a state that is entitled to elect one member to the House of Representatives. There are currently 435 voting members of Congress representing all 50 states. American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, the US Virgin Islands, and the District of Columbia have one non-voting member each. Congressional districts with non-voting members are numbered 98 (e.g. DC-98).
States with relatively small populations (Alaska, Delaware, Montana, North Dakota, South Dakota, Vermont, and Wyoming) have only a single district. Congressional districts in these single-district states are numbered 00 (e.g. VT-00).
Congressional district boundaries are redrawn after each decennial census. Data is current updated to reflect the latest information for the 119th Congress. Smaller adjustments to district boundaries may occur between major redistricting. With the exception of mid-decade redistricting, Congressional district boundaries drawn as part of the 2020 redistricting cycle will remain in effect until the next round of redistricting, scheduled to follow the 2030 census.
Shorelined and unshorelined versions of the boundary data is included.
