In the News: The Nigerian Census

Small wonder, then, that the country hasnโ€™t conducted a census since 1991โ€”which some analysts think undercounted Nigeriaโ€™s population (officially put at 89 million) by perhaps 20 million people. (Estimates put the current total population at between 120 million and 150 million people.)3

But Nigeria isnโ€™t alone: 15 countries worldwide have not taken a census since 1990โ€”most because of ongoing conflict, but some because of a simple lack of resources.4 Perhaps more remarkable, many of the poorest developing countries (such as the Central African Republic, Niger, and Yemen) have been able to hold censuses since 2000.5 โ€œCensus taking doesnโ€™t just provide an update of many national parameters such as total population, fertility, age, and sex,โ€ says Carl Haub, senior demographer at the Population Reference Bureau. โ€œIn the case of developing countries, it provides an up-to-date sampling frame for badly needed demographic surveys.โ€

(April 2006) Census taking seems a quiet affair to most people in the United States, where the head count runs relatively smoothly and is reliably decennial. But in Nigeria, last monthโ€™s national census was met with protests, boycotts, charges of fraud, and at least 15 deaths.1 Thousands of other enumerators walked off the job because they hadnโ€™t been paid, and many people in large swaths of the country say they still havenโ€™t been counted.2

Passion and conflict are nothing new for Nigerian censuses. Their results decide the division of federal money and the balance of political power in a nation split almost evenly between a largely Muslim population in the North (which has traditionally controlled the government) and the coastal, more-urbanized, and largely Christian South, which regularly accuses northerners of rigging the census for political gain (see Table 1).

The final results of the Nigerian 2006 Censusโ€”which marshaled almost 1 million enumerators and cost $266 million, more than one-half of which was paid for by the European Union and other international donorsโ€”are scheduled to be announced in mid-2006.6 And the Nigerian government has said it will use the results to guide political redistricting before the countryโ€™s 2007 general elections.7 But if past is prologue, that deadline might be missed: The 2006 Census was originally supposed to be held in 2001.

DHS Results for Nigeriaโ€™s Religious and Geographic Demography

Ethnic and religious violence has killed at least 14,000 people in the past seven years in Nigeria, a country containing at least 250 different ethnicities and at least as many languages.8 Splits between Nigerian Muslims and Christians and among the countryโ€™s ethnic groups are so incendiary that census officials decided to not ask citizens this year about their religious affiliation or ethnicity. That decision inflamed Christians, who have refused to accept past census results that they are in a slight minority compared with Muslims.9

The controversy isnโ€™t just about religious pride. Census numbers in Nigeria guide political redistricting, the distribution of oil revenues, and even civil service hiring. (Nigeriaโ€™s constitution dictates that the relative population percentages of every ethnic and religious group must be used to determine the mix of those groups in all federal appointmentsโ€”including the armed forces.10) The 2006 Census does ask people where they live, which can serve as a crude index of ethnic or religious affiliation because these groups are often highly geographically concentrated.

While the 2006 Census will be silent on religion or ethnic identity, a 2003 Demographic and Health Survey (DHS) taken in Nigeria gives a reliable portrait of how the countryโ€™s population breaks down along these lines. The sampling frame for the 2003 Nigeria DHS used the list of enumeration areas developed for the countryโ€™s 1991 Census. Muslims made up just over 50 percent of the countryโ€™s population, while Christians were about 48 percent (see Table 1).

The split between Nigeriaโ€™s northern and southern regions has further complicated both Nigerian politics and census taking. The Northโ€™s political strength arose initially from the results of the 1952-3 Census, which showed 54 percent of the countryโ€™s population resided in that area.11

While the last five censuses were all held under military strongmen from the North, Nigeriaโ€™s current president, Olusengun Obasanjo, hails from the South, making him the first elected president from that region. Some analysts have accused Obasanjo, who is trying to amend Nigeriaโ€™s constitution to allow him a third term in office, of using the 2006 Census to divert public attention away from his political troubles.12

In 2003, around 60 percent of Nigeriaโ€™s population lived in the countryโ€™s northern region (see Table 2), ratifying that areaโ€™s longstanding claim of containing the majority of Nigerians. And Nigeriaโ€™s regional total fertility rates (TFR, the average number of children a woman will have during her lifetime) suggest that this northern predominance in population will continue. As Table 3 shows, northern Nigeriaโ€™s three geopolitical zones all have higher TFRs than those found in the countryโ€™s southern zones.

According to data from PRBโ€™s 2005 World Population Data Sheet, if Nigeriaโ€™s North East zone were a separate country, its TFR of 7.0 would be tied for the fourth-highest in the worldโ€”behind only Niger (8.0), Guinea-Bissau (7.1), and Mali (7.1).13 Nearly one in every six women ages 15-49 in that zone were pregnant in 2003.

The Difficulty of Taking a Census in Some Countries

Nigeriaโ€™s difficulties at census taking have even been the butt of international jokes. In April 2005, for instance, Ugandaโ€™s environment minister, Kahinda Otafiire, called the opposition party in Uganda unfit to govern and compared them to โ€œNigerians who donโ€™t know how to count themselves.โ€14

The jibe was quickly protested by Nigerian officials. But taking a census is no laughing matter in many countries torn by strife or short on resources for such a nationwide effort (see Table 4).

โ€œCensus taking in many developing countries is a particularly difficult process,โ€ says Haub, โ€œgiven shortages in educated staff to act as enumerators and the funds to train them, poor road and transportation networks, general suspicion of governments, ethnic rivalries, and outright armed conflict in some cases.โ€

And some observers dispute that the 2006 Nigerian Census was comprehensive. Indeed, a day before the five-day headcount was scheduled to end, Nigeriaโ€™s national population chairman, Samuโ€™ila Danko Makama, admitted that only 70 percent of the country had been canvassed.15 (The census was ultimately extended two extra days.)

Census forms and materials were also reported in short supply, especially during the first two days of the count, when people were ordered to stay home from work to ensure accurate enumeration. And many people claim to have been missed by census workers entirely. More than 45,000 herders in northeastern Yobe state, for instance, were left uncounted by the end of the censusโ€”simply because they had not been included in the official census map.16
