The fight for more elbowroom and breathing space just became a little more difficult.

As of Oct. 31, the world is officially home to seven billion people.

Demographers from the United Nations Population Division chose the last day of October as the symbolic date for this milestone. However, it’s acknowledged the selection of a precise date or time is impossible.

There are several international sources that claim the chosen emblematic date is inaccurate.

The U.S. Census Bureau claims their alternative method of calculating puts the seven billion mark in March 2012.

The Vienna Institute of Demography in Europe uses a large time frame in their estimation, reckoning the number will be reached anywhere between February 2012 and July 2014.

In a recent report conducted by the UN Population Fund, it was revealed that Asia accounts for 60 per cent of the world’s population. Not surprisingly, the world’s official seven billionth baby is from there.

Danica May Camacho – who was born two minutes before midnight in Manila, Philippines – was chosen as the first child to symbolize reaching the seven billion milestone by the UN.

The UN also predicts the eight billion threshold will be surpassed by 2025. When compared to the time frame between a population of three billion in 1959 and a population of four billion in 1974, things have sped up significantly.
