Nigeria
Population of Nigeria
Nigeria has experienced a population explosion for at least the last 50 years due to very high fertility rates, quadrupling its population during this time. Growth was fastest in the 1980s, after child mortality had dropped sharply, and has slowed slightly since then as the birth rate has sunk slightly. According to the 2012 revison of the World Population Prospects the total population was 159,708,000 in 2010, compared to only 37,860,000 in 1950. The proportion of children below the age of 15 in 2010 was 44.0%, 53.2% was between 15 and 65 years of age, while 2.7% was 65 years or older.
Health in Nigeria
Health care provision in Nigeria is a concurrent responsibility of the three tiers of government in the country.Private providers of health care have a visible role to play in health care delivery.
Administrative structure of Nigeria
Nigeria is divided into thirty-six states and one Federal Capital Territory, which are further sub-divided into 774 Local Government Areas (LGAs). The plethora of states, of which there were only three at independence, reflect the country's tumultuous history and the difficulties of managing such a heterogeneous national entity at all levels of government.
