As in the UK Parliament the constituencies were classified as borough, county or university constituencies.

From 1921 to 1929, the 52 Members of Parliament were elected using proportional representation by the single transferable vote in multi-member constituencies established under the Government of Ireland Act 1920, which also established the same constituencies as one-member or two-member constituencies to the UK Parliament.

Between 1929 and 1969, under the House of Commons (Method of Voting and Redistribution of Seats) Act (Northern Ireland) 1929, there were 48 single-member constituencies, elected by first past the post. The non-territorial Queen's University of Belfast constituency continued to return 4 members using the single transferable vote.

From the 1969 election, under the Electoral Law Act (Northern Ireland) 1968, university representation was ended and 4 new territorial constituencies were created. The 52 constituencies ceased to exist after the Parliament of Northern Ireland was suspended in 1972 and abolished in 1973.
