Population

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:

    In our large cities, the population is godless, materialized,—no bond, no fellow-feeling, no enthusiasm. These are not men, but hungers, thirsts, fevers, and appetites walking. How is it people manage to live on,—so aimless as they are? After their peppercorn aims are gained, it seems as if the lime in their bones alone held them together, and not any worthy purpose.
    Ralph Waldo Emerson (1803–1882)

    [Madness] is the jail we could all end up in. And we know it. And watch our step. For a lifetime. We behave. A fantastic and entire system of social control, by the threat of example as effective over the general population as detention centers in dictatorships, the image of the madhouse floats through every mind for the course of its lifetime.
    Kate Millett (b. 1934)
