Congressional district

From ModelUSGov Wiki

Congressional districts, also known as electoral districts, legislative districts, wards and electorates in other nations, are divisions of a larger administrative region that represent the population of a region in the larger congressional body. Notably, in Australia, electoral districts are referred to as "electorates" or "seats"; in Canada these are called "constituencies" or more informally "ridings". Countries with congressional districts include the United States, the Philippines and Japan.
