World population may double by 2100 base on decision today – says UN

The policies of population-control today can result in widely different number of global population by 2100, said the United Nations Population Fund (UNFPA).

According to the study cited by UNFPA spokesperson, Mette Strandlod, the global population may reach 16.6 billion by 2100, which is a 9.2 billion increase from the current figure of around 7.4 billion, if the fertility rate continues to increase.

Likewise, the world’s population may be 11.2 billion or 7.3 billion by 2100 if it has a medium or low fertility rate respectively.

“The key is to allow women to have the number of children that they want to have,” said Strandlod at UN City, Copenhagen.

The UNFPA spokesperson added that the accessibility to contraception for women plays an important role in how the global population changes in the next 84 years.

Correction: A previous version of this article incorrectly stated that the United Nations projected global population to the year 2011. In fact, the projected year is 2100.
