It would be more accurate to bring up the expanding population of Humanity The world reached one billion for the first time in 1804. It would be more than 100 years before it reached two billion in 1927, but it took only 33 years to reach three billion in 1960. Thereafter, the global population reached four billion in 1974, five billion in 1987, six billion in 1999 and, by some estimates, seven billion in October 2011 There are more people living in more places then ever before.
