South Africa Population growth rate. Factbook > Countries > South Africa > Demographics. Population growth rate: 0.99% (2016 est.) Definition: The average annual percent change in the population, resulting from a surplus (or deficit) of births over deaths and the balance of migrants entering and leaving a country. The rate may be positive or negative.
With similar annual growth rate, the population is likely to stand at 34,762,000 in 2015 and 66,305,000 by 2050. Although population per square kilometer was only 241 in 1999 (93 per square mile), the above projected population growth could create a future crisis of land and resources.
