Tanzania population growth

One Billion Tanzanians, One Billion Ugandans

It struck me to find out that according to the UN’s official projections, populations of Tanzania and Uganda would exceed one billion people by 2100 (up from 45 and 33 million, respectively, in 2010) if total fertility rates in each of these countries remain constant at their 2010 levels (5.6 and 6.4 children per woman, respectively).

To be sure, this “constant fertility scenario” is not a likely one. For a number of reasons, fertility rates tend to fall as economies develop, and the process of demographic transition from high mortality and high fertility to low mortality and low fertility is already under way in both countries. Still, even under assumption that total fertility rates will gradually decline to about 2 children per woman (and there is no international migration), the UN estimates that there will be 171 million Ugandans and 316 million Tanzanians in 2100.

Can Tanzania afford 100 million citizens in 2035?

Let's think together: Every week the World Bank team in Tanzania wants to stimulate your thinking by sharing data from recent official surveys in Tanzania and ask you a couple of questions. This post is also published in the Tanzanian newspaper The Citizen every Sunday.

Tanzania has experienced an exceptionally high population growth – from 11 million in 1963 to over 45 million in 2012. Among the factors that have contributed to this increase –one of the fastest in the world– is the falling mortality rate. Life expectancy in Tanzania has increased over the past two decades from 50 to 58 years. 

In addition, Tanzanian women have continued to have many children (5.4 per woman in 2010), which is higher than Kenya and Rwanda (4.6) as well as other sub-Saharan countries with the exception of Uganda.
Since 1991, this rate has only declined by 13 percent in Tanzania against 26 and 31 percent in Rwanda and Kenya, respectively.  Several other factors have also contributed to the high population growth rate that Tanzania is experiencing:
