According to the United Nations’ World Population Prospects – Revised Version for 2015, Tanzania’s population currently at 53,470 million, is expected to more than double by the year 2050 increasing its annual contribution to the global population growth from 1,564 million in 2015 to 2,975 million in 2050.
This 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 DR 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 137,136 million by 2050, among those countries representing over 60% of the world’s population with India heading the list.
Among other findings that the report highlights are the Tanzania’s median age which 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.
In addition, 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.
The United Nations Population Fund (UNFPA) comes working closely with the Tanzanian Government designing and implementing programmes related to reproductive health, population and development, to ensure economic development, social equality and improvements in maternal and infant mortality rates.
