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 is a puzzling place today. All these banks sending us credit cards, with our names on them. Well, we didn’t order any credit cards! We don’t spend what we don’t have. So we just cut them in half and throw them out, just as soon as we open them in the mail. Imagine a bank sending credit cards to two ladies over a hundred years old! What are those folks thinking?”
—Sarah Louise Delany (b. 1889)
“The human face is a weak guarantee; yet it deserves some consideration. And if I had to whip the wicked, I would do so more severely to those who belied and betrayed the promises that nature had implanted on their brows; I would punish malice more harshly when it was hidden under a kindly appearance.”
—Michel de Montaigne (1533–1592)
“America is like one of those old-fashioned six-cylinder truck engines that can be missing two sparkplugs and have a broken flywheel and have a crankshaft that’s 5000 millimeters off fitting properly, and two bad ball-bearings, and still runs. We’re in that kind of situation. We can have substantial parts of the population committing suicide, and still run and look fairly good.”
—Thomas McGuane (b. 1939)
