A 002 WORLD POPULATION

  WORLD POPULATION  

The world population is the total number of living humans on the planet Earth, currently estimated to be 6.94 billion by the USA Census Bureau  as of July 1, 2011.  The world population has experienced continuous growth since the end of the Bubonic Plague, Great Famine and Hundred Years Wars in 1350, when it was about 300 million

It is estimated that the population of the world reached one billion in 1804, two billion in 1927, three billion in 1960, four billion in 1974, five billion in 1987, and six billion in 1999. It is projected to reach seven billion in October 2011, and around eight billion by 2025–2030. By 2045–2050, the world's population is currently projected to reach around nine billion, with alternative scenarios ranging from 7.4 billion to 10.6 billion. Projected figures vary depending on such things as the underlying assumptions and which variables are manipulated in projection calculations, especially the fertility variable. Such variations give long-range predictions to 2150, ranging from population decline to 3.2 billion in the 'low scenario', to high scenarios of 24.8 billion, or soaring to 256 billion assuming fertility remains at 1995 levels.

There is no estimation on the exact day or month the world's population surpassed both the one and two billion marks. The day of three and four billion were not officially noted, but the International Database of the United States Census Bureau places them in July 1959 and April 1974. The United Nations did determine, and celebrate, the "Day of 5 Billion" (11 July 1987), and the "Day of 6 Billion" (12 October 1999). The International Programs division of the United States Census Bureau estimated that the world reached six billion on 21 April 1999 (several months earlier than the official United Nations day). The "Day of 7 Billion" has been targeted by the United States Census Bureau to be in March 2012, while the Population Division of the United Nations suggests 31 October 2011.

In the long run, the future population growth of the world is difficult to predict and the UN and US Census Bureau give different estimates. According to the latter, world population will hit seven billion in July 2012 or by late 2011, according to UN prediction.

Birth rates are declining slightly on average, but vary greatly between developed countries (where birth rates are often at or below replacement levels), developing countries, and different ethnicities. Death rates can change unexpectedly due to disease, wars and catastrophes, or advances in medicine. 

The UN has issued multiple projections of future world population, based on different assumptions. Over the last ten years, the UN has consistently revised these projections downward, until the 2006 revision issued March 14, 2007 revised the 2050 mid-range estimate upwards by 273 million.
