For parliamentary elections, the country is divided into more than 543 electoral constituencies. A constituency is usually made on the basis of population of a particular geographical area. Similarly, assembly constituencies are made in different states for the elections to the state assemblies. Voters in a constituency elect their representative.
An electoral district (also known as a constituency, riding, ward, division, electoral area or electorate) is a distinct territorial subdivision for holding a separate election for one or more seats in a legislative body. Generally, only voters who reside within the geographical bounds of an electoral district (constituents) are permitted to vote in an election held there.
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 “Chûnāô Kshetra”(Hindi: चुनाव 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 “Chûnāô-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 the Hindi terminology(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.
