Introduction
Population in Nigeria increased from 1990 to 2008 by 57 million, 60% growth rate. Nigeria is the most populous country in Africa and accounts for about 18% of the continent’s total population, however, exactly how populous is a subject of speculation.
The United Nations estimates that the population in 2009 was at 154,729,000, distributed as 51.7% rural and 48.3% urban, and with a population density of 167.5 people per square kilometer. National census results in the past few decades have been disputed. The results of the most recent census were released in December 2006 and gave a population of 140,003,542. The only breakdown available was by gender: males numbered 71,709,859, females numbered 68,293,08. On June 2012, President Goodluck Jonathan said that Nigerians should limit their number of children.
