Population: 162,471,000 (July 2011 United Nations est.)
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 2010 revison of the World Population Prospects the total population was 158 423 000 in 2010, compared to only 37 860 000 in 1950. The proportion of children below the age of 15 in 2010 was 42.8%, 53.8% was between 15 and 65 years of age, while 3.4% was 65 years or older .

Famous quotes containing the word population:
“What happened at Hiroshima was not only that a scientific breakthrough ... had occurred and that a great part of the population of a city had been burned to death, but that the problem of the relation of the triumphs of modern science to the human purposes of man had been explicitly defined.”
—Archibald MacLeish (1892–1982)
“The most advanced nations are always those who navigate the most. The power which the sea requires in the sailor makes a man of him very fast, and the change of shores and population clears his head of much nonsense of his wigwam.”
—Ralph Waldo Emerson (1803–1882)
