Terminology
In American English, the term congressional district is used. The term "congressional district" is largely used in the United States and is distinctive from legislative districts. In the United States, congressional districts were inscribed into the Constitution to ensure representation based on population. Conversely, state legislation declares that "legislative representation be (built upon) non-population related principles such as representation of counties, cities, or other geographical and political unit".
