World Population Growth

World Population Growth - 1800 to 2100


World population is forecast to grow by a third over the next 40 years.

This is the predicted amount of growth. Like most population predictions it is based on historical trends.

There could well be disruptions that could change the predictions, eg. resources, in particular food and water shortages will effect many countries.  Most of this growth will occur in developing countries.

Population growth is slowing – but this is largely due to declining fertility rates in developed countries (e.g. western European countries).
