How Tanzania's population is changing
Tanzania records about 6,722 births and 1,105 deaths a day. That is a natural increase of roughly 5,617 people per day, or about 2.05 million a year before migration is counted.
Net migration runs at about 12,730 over the reported period, with more people leaving than arriving. That is small next to its natural change.
If the current rate held indefinitely, Tanzania would take roughly 25 years to double in size — a projection of today's rate, not a forecast.
Over the 9 years from 2016 to 2025, the population rose from 53.8 million to 70.5 million — a gain of 16.7 million, or 31.1%.
Where people live in Tanzania
With about 75 people per square kilometre, Tanzania is moderately populated, roughly 1.2× the world average of 62. That ranks 69th of the 115 countries here. Its closest comparisons on density are Tajikistan and Yemen.
Tanzania covers about 885,800 km² of land, which is what turns a population of 70.5 million into that density figure.
About 36.9% of people live in urban areas, making Tanzania split between town and countryside, below the world average of 57.8%. That works out to roughly 26.0 million town and city dwellers and 44.5 million living rurally.
Age, fertility and life expectancy in Tanzania
Tanzania has a very young population: about 42.3% are under 15 and 3.0% are 65 or older. Children outnumber over-65s by roughly 13.9 to one.
The total fertility rate is about 4.54 births per woman, above the ~2.1 replacement level, which is what sustains growth from births alone. The world figure is about 2.19.
Life expectancy at birth is about 67.2 years, roughly 6.3 years below the global average of 73.5.
