Niger has three types of constituencies for elections to the National Assembly (Assemblee nationale): ordinary, special, and diaspora. Ordinary constituencies correspond to the seven regions of Niger and the capital district of Niamey. All special constituencies are single-member constituencies reserved for national minorities. Beginning in 2016, Nigeriens living outside of the country could elect MPs from a new diaspora constituencies.

The following table shows the apportionment of seats:

NIGER 1 (1993-9)
In 1993, the National Assembly had 83 members with 75 allocated to ordinary constituencies and 8 to special constituencies. There was no legal threshold to win seats.

In ordinary constituencies, the largest remainder system of proportional representation with a Hare quota was used to allocate seats off of closed lists within each constituency. The Hare quota equals the total number of valid votes in a constituency divided by the number of mandates in the constituency. Seats were awarded for multiples of full Hare quotas with any leftover seats given out to parties in descending order of remainder votes (i.e. votes not used towards a full Hare quota and seat). Lists were closed.

In special constituencies, the winner was determined by the single-member plurality electoral system.
