Assembly and Lok Sabha constituencies: what is the difference?
Direct answer
An Assembly constituency elects an MLA to the state legislature. A Lok Sabha constituency elects an MP to the House of the People in Parliament. Tamil Nadu has 234 Assembly constituencies and 39 Lok Sabha constituencies.

One address, two forms of representation
A voter’s address belongs to an Assembly constituency and a parliamentary constituency. These elections are for different institutions. An Assembly result does not identify the MP, and a Lok Sabha result does not identify the MLA.
The Constitution defines Parliament and state legislatures separately. Whether you are seeking an Assembly debate or a parliamentary debate determines which institutional record to open.
Names do not establish identical boundaries
A parliamentary constituency can contain multiple Assembly segments. Seats sharing a place name need not cover the same area. District boundaries and electoral boundaries also serve different purposes.
When looking up an Assembly seat such as Mylapore, identify its AC number first. A Chennai district report does not by itself establish that an event occurred inside Mylapore; a direct mention of the seat matters.

Choose the record for the question
For an MLA, check the Tamil Nadu Assembly member directory. For an MP election result, check the parliamentary-election record. Read whether the result heading says Assembly or Parliamentary Constituency.
Include the election type and year when sharing a vote total. Presenting an Assembly result as a result for a larger parliamentary seat misidentifies both the representative and the electorate.

Wards and panchayats are another level
A municipal ward, panchayat or district is not another name for an Assembly or Lok Sabha constituency. Do not describe a local-government representative as an MLA or MP.
For a service complaint, establish the responsible authority from the service’s official record. A constituency map alone does not determine which department or officer owns that service.
Frequently asked questions
Are Assembly and Lok Sabha votes separate?
They elect different offices. Even if polling occurs together, the results remain separate; winning one does not make the candidate a member of the other institution.

Does each district have just one MLA?
No. A district and an Assembly seat are different units. Identify the Assembly constituency rather than relying on the district name.
What do 234 and 39 refer to?
Tamil Nadu’s 234 Assembly constituencies and 39 parliamentary constituencies, not district counts or seats won by a party.
