The National Population Commission (NPC) is a Nigerian government agency established by Section 140 (1) of the 1979 Constitution of the Federal Republic of Nigeria. However, it was suspended on 31 December 1983, following a military takeover of the democratically elected government of Nigeria.^[8] The commission was re-established by the National Population Commission Decree No. 23 of 1989, which is now known as the National Population Act, CAP – No_67, Law of the Federal Government of Nigeria (LFN) 2004. The 1999 Constitution of the Federal Republic of Nigeria (as amended), under section 153 (i) (j) and part of (i) (j) of the third Schedule to the Constitution, and Births, Deaths, etc. (Compulsory Registration) Act, CAP B9, LFN 2004.^[9][6]

The Commission has the statutory powers to collect, analyse and disseminate population and demographic data in the country. It is also mandated to undertake demographic sample surveys, compile, collate and publish migration and civil registration statistics as well as monitor the country's population policy.^[1]

Prior to 1979, the Commission was known as the National Census Board, and conducted the 1973 Census. It was headed by Justice Adetokunbo Ademola. It was a temporal body which was later transformed into the National Population Bureau. In 1981, President Shehu Shagari inaugurated Alhaji Abdulrahman Okene, as chairman of the commission, alongside 19 members representing each state of the federation.

When General Muhammadu Buhari overthrew the Shagari presidency on 31 December 1983, the constitution was suspended and the commission was dissolved. The commission reverted to the status of a Bureau, and was headed by a civil servant on the rank of director.

In 1988, Alhaji Shehu Musa, Makaman Nupe was appointed by General Ibrahim Badamosi Babangida, as chairman of the commission alongside six members. The commission was legalized with Decree No 43 of 1989. This commission conducted the 1991 census.

Empowered by the 1999 Constitution, in October 2001, the Olusegun Obasanjo administration inaugurated Chief Samu’ila Danko Makama as chairman of the Commission alongside 37 members representing each state in Nigeria and the FCT.

In June 2012 Chief Eze Festus Odimegwu was inaugurated as chairman of the commission alongside 37 members, one each from the 36 states of Nigeria, and one representing the Federal Capital Territory. Odimegwu resigned in October 2013. In February 2014, Eze Duruiheoma, SAN was appointed Chairman of the commission.^[10]

On 15 October 2020, the Senate of Nigeria confirmed the appointment of Nasir Isa Kwarra as the chairman and eleven commissioners for the Commission.^[11]

With the census Ordinance of 1863, the first population census in the Nigeria area was conducted in 1866.^[12] Subsequent ones were held in 1871, 1881, 1891 and 1901. These counts were all confined to the Lagos Colony and its environs, and marked the sequential beginning of the British decennial census tradition in Nigeria.

The 1911 census covered the entire Southern Protectorate. However, the enumeration was not total because some areas had not yet accepted the authority of the colonial government.

The amalgamation of the Southern and Northern protectorates in 1914 by Lord Lugard widened the census coverage in Nigeria. Like in previous censuses, the results of the 1921 population estimates were based on tax records, and people who had not filed a tax return were not counted. In the Northern region, the population estimates were based on vital statistics.^[10]

The Women's War of 1929 in Calabar and Owerri provinces in the Eastern region prevented the enumeration of major municipalities in these areas in 1931. Similarly, some areas in the Northern provinces were not counted as some census staff were re-posted to anti-locust duties as a result of the raging locust invasion in some parts of the North.

The outbreak of the Second World War broke the sequential chain of the decennial counts as no population count was conducted in 1941. The 1952/1953 Population Census was marred by gross under-enumeration as people were suspicious of the motives of the exercise having been broken by the Second World War.^[10]

The 1962 population census was simultaneously held across the nation. The census was highly politicized. All the regional governments rejected the results. This led to a rerun in 1963 which was still contested at the Supreme Court, where the court declined jurisdiction over administrative functions of government.

The census of 1973 was also not gazetted for reasons of falsification of figures for political and ethnic advantages. The 1991 Census employed the principle of simultaneity. It was scientifically conducted, accepted, and gazetted. The first population and housing census held in 2006. It employed the use of GPS and satellite imagery to mark-out Geo-referenced enumeration areas.

Below is the National Summary of the 1991 population census, which used the de facto method.

The growth rate of 2.83% per annum was used to project the population to 1996, giving a mid-year population of 102.5 million in 1996.^[19]

Below is the national summary of the 2006 national population census, which used the de facto method.

The annual exponential growth rate was 3.18 percent, between the period of the two Censuses of 1991 and 2006 which was 14 years and 4 months. The sex ratio (number of males per 100 females in the population) was approximately 103 at the national level.^[20]

Eze Festus Odimegwu who was appointed Chairman, National Population Commission (NPC), in June 2012, He made several unguarded statements amongst which was his condemnation of the census of 2006. He also said Nigeria has never had a credible population census. Population census in Nigeria carries political and religious implications, thus, some Nigerians, especially of Northern extraction rose in opposition to his comments.^[21]

Governor of Kano State in Northern Nigeria, Rabiu Kwankwaso, visited President at the time Goodluck Jonathan and demanded the dismissal of Odimegwu. He was issued a query, and later forced to resign a year into his four-year tenure.^[22]
