The world population - the total number of humans alive on the planet Earth at a given time. According to estimates published by the world population in June 2005 was ~6,450,000,000. 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.
