Nigeria’s 109 Senatorial Districts, 360 House of Representatives constituencies

Nigeria has a bicameral (two-chamber) federal legislature, namely the upper chamber: House of Senate or Senate (for short) and the lower chamber: House of Representatives. The Senate has 109 Senators elected from the 109 Senatorial Districts, 3 per each of the 36 states and 1 from Abuja, the Federal Capital Territory. The House of Representatives has 360 elected members from 360 constituencies. The House of Reps constituencies are usually 1 per Local Government Area (LGA) but some relatively less populated LGAs are combined to make a constituency.


The Senatorial Districts are provided for by the constitution of Nigeria. Chapter 5, Part 1, Section 71 of the constitution talks about Senatorial Districts. INEC got empowered to create the senatorial districts. Subject to the provisions of section 72 of the Constitution, the Independent National Electoral Commission shall divide each State of the Federation into three Senatorial districts for purposes of elections to the Senate.

The formation of the Senate is based on the three Senatorial Districts per State and one for the Federal Capital Territory. The 109 member Senate is presided over by the President of the Senate and assisted by the Deputy President of the Senate, all are chosen among the Senators. They are then assisted by eight Principal Officers and several Committee Chairmen and Vice Chairmen.

The eight Principal Officers include Majority Leader, Deputy Majority Leader, Minority Leader, Deputy Minority Leader, Chief Whip, Deputy Chief Whip, Minority Whip and Deputy Minority Whip.

As the highest lawmaking institution in Nigeria, the Senate is constitutionally vested with the power of making laws for the good governance of the country.  It is empowered to represent the interest, yearnings, aspirations and wellbeing of the citizenry. It has the power of scrutinizing public institutions and officials to ensure accountability.


The Senate also intervenes in matters of urgent national issues and matters of national interest like insecurity, epidemic, drought, poverty, illiteracy, flood and others.
