World Human Population
As of today's date, the world population is estimated by the United States Census Bureau to be 7.054 billion. The US Census Bureau estimates the 7 billion number was surpassed on 12 March 2012. According to a separate estimate by the United Nations, Earth’s population exceeded 7 billion in October 2011, a milestone that offers unprecedented challenges and opportunities to all of humanity, according to UNFPA, the United Nations Population Fund.
According to papers published by the United States Census Bureau, the world population hit 6.5 billion (6,500,000,000) on 24 February 2006. The United Nations Population Fund designated 12 October 1999 as the approximate day on which world population reached 6 billion. This was about 12 years after world population reached 5 billion in 1987, and 6 years after world population reached 5.5 billion in 1993. The population of some countries, such as Nigeria, is not even known to the nearest million, so there is a considerable margin of error in such estimates.
Researcher, Carl Haub, calculated that a total of over 100 billion people have probably been born in the last 2000 years.

Famous quotes containing the words world, human and/or population:
“The world must be peopled. When I said I would die a bachelor, I did not think I should live till I were married.”
—William Shakespeare (1564–1616)
“Human life consists in mutual service. No grief, pain, misfortune, or “broken heart,” is excuse for cutting off one’s life while any power of service remains. But when all usefulness is over, when one is assured of an unavoidable and imminent death, it is the simplest of human rights to choose a quick and easy death in place of a slow and horrible one.”
—Charlotte Perkins Gilman (1860–1935)
“The population question is the real riddle of the sphinx, to which no political Oedipus has as yet found the answer. In view of the ravages of the terrible monster over-multiplication, all other riddle sink into insignificance.”
—Thomas Henry Huxley (1825–95)
