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.

“The child who would be an adult must give up any lingering childlike sense of parental power, either the magical ability to solve your problems for you or the dreaded ability to make you turn back into a child. When you are no longer hiding from your parents, or clinging to them, and can accept them as fellow human beings, then they may do the same for you.”
—Frank Pittman (20th century)
“O for a man who is a man, and, as my neighbor says, has a bone in his back which you cannot pass your hand through! Our statistics are at fault: the population has been returned too large. How many men are there to a square thousand miles in this country? Hardly one.”
—Henry David Thoreau (1817–1862)
