Legislative district

An electoral district (also known as a constituency, legislative district, riding, ward, division, electoral area, or electorate) is a territorial subdivision for electing members to a legislative body. Generally, only voters (constituents) who reside within the district are permitted to vote in an election held there. From a single district, a single member or multiple members might be chosen. Members might be chosen by a first-past-the-post system or a proportional representative system, or another voting method entirely. Members might be chosen through a direct election under universal suffrage, an indirect election, or another form of suffrage.

The names for electoral districts vary across countries and, occasionally, for the office being elected. The term constituency is commonly used to refer to an electoral district; it can also refer to the body of eligible voters within the represented area. Similarly, in Australia and New Zealand, electoral districts are called electorates, however elsewhere the term electorate generally refers specifically to the body of voters. In India electoral districts are referred to as "Nirvachan Kshetra" (Hindi: निर्वाचन क्षेत्र) in Hindi, which can be literally translated to English as "electoral area" though the official English translation for the term is "constituency". The term "Nirvachan Kshetra" is used while referring to an electoral district in general irrespective of the legislature. When referring to a particular legislatorial constituency, it is simply referred to as "Kshetra" along with the name of the legislature, in Hindi (e.g.-'Lok Sabha Kshetra' for a Lok Sabha Constituency). Electoral districts for municipal or other local bodies are called "wards". In Canada, districts are colloquially called ridings (stemming from an earlier British geographical subdivision); in French, circonscription or (colloquially) comté, "county." Local electoral districts are sometimes called wards, a term which also designates administrative subdivisions of a municipality. In local government in the Republic of Ireland voting districts are called "electoral areas".
