The world population is the total number of humans alive on the planet Earth at a given time. According to estimates published by the United States Census Bureau, the world population in June 2005 was ~6,450,000,000. In line with population projections, this figure continues to grow at rates that are unprecedented prior to the 20th century. Approximately one fifth of all humans in the last six thousand years are currently alive. By some estimates, there are now one billion (thousand million) young people in the world between the ages of 15 and 24.Contents[hide]1 When was six billion reached? 2 Rate of population increase 3 Forecast of world population 4 Doomsayers 5 Different continents 6 References 7 External links When was six billion reached?The United Nations Population Fund designated October 12, 1999 as the approximate day on which world population reached six billion. This was about 12 years after world population reached five billion, in 1987. The child that has been proclaimed by the United Nations Population Fund and welcomed by the U.N. Secretary-General Kofi Annan as the six billionth baby, was born on the designated day two minutes after midnight, not in India or China, as might be expected, but to Fatima Nevic and her husband Jasminko in Sarajevo, Bosnia.
