Tanzania’s population of 53.4m in 2015 is expected to more than double by 2050, increasing its annual contribution to the global population growth from 1.6m in 2015 to nearly 3m in 2050.
Tanzania’s median age is expected to grow from a current 17.3 years to 22.2 years by 2050, placing the country among the 10th youngest populations in the world.
This is indicated in the latest United Nations’ World Population Prospects – Revised Version for 2015.
The projected increase in Tanzania’s population would move the country from the current 14th position with 1.9% growth contribution, to the 4th position with 5.5% in 2050 behind Nigeria, India and the Democratic Republic of Congo.
Tanzania, which is ranking today at the 26th position in the list of countries representing 75.1% of the world’s population, would rank as the 14th largest country with an expected population of 137m by 2050.
The fertility rate measured as the number of children in a female’s lifetime, would be reduced from a current 5.24, considered as a high-fertility country, to 3.42 by 2050.
Mortality and under-five mortality rates measured as deaths per 1,000 births, would improve from 37 and 51.5 to 19.1 and 24.2, while life expectancy at birth is expected to grow from the current 64.0 years to 74.2 in the same period.
