Population increase could reach 16 billion by 2100

Population increase could reach 16 billion by 2100, says a new report by the UN Population Division.

By the 22nd century, the population of the world could be as small as six billion, a number we’ve already surpassed, or as high as 16 billion, which could put a strain on food resources.

Hania Zlotnick, head of the UN Population Division, says what’s projected is the median variant – or number– that population will continue to increase for the remainder of the century to about 10 billion from the current nearly seven billion in the world today.

What will determine the number of people alive by the year 2100 is the number of children on average couples have during the next 90 years. Ms. Zlotnick explains.

“The high variant projects half a child above that path and the low variant projects half a child below that path. So this big range of possible future populations are determined by very small changes in the level of fertility that countries might have in the future.”

The population projections can be found in the 2010 Revision of World Population Prospects, prepared by the UN Population Division. The report says 39 high fertility countries are in Africa, but nearly 20 are spread across Latin America, Asia and Oceania.
