The population of Africa is SEVERELY overestimated
Over the past month I’ve been autistically working on an excel sheet cataloging African demographic figures (birth rates, TFR, pop., etc). The population numbers and statistics for Africa are totally unreliable. Fertility and total population are all wrong. my methodology is simply going to the national statistics office of every country and comparing them to the UN / WorldBank figures. For countries in which there are no reliable statistics, I just average the sum of percentage discrepancies in realized UN data errors in (based on reporting by Jesus Fernandez Villaverde) that we have on hand and VERY roughly extrapolate to the unknown data.
The unavoidable conclusion is that the numbers for Africa are maximally unreliable. There are various reasons for this that we can speculate on, (lack of state capacity, foreign aid dependency, etc) but take any official numbers with a grain of salt.
To give some examples…
Ethiopia UN figure (2024) - 129-132M people
Ethiopia 2025 census figure - 111M people (difference of ~21 MILLION people, an 18% discrepancy). (Ethiopia may poltical reasons to actually underestimate its pop. but given increasing urbanization + lack of state capacity in rural areas + faulty previous baked-in projections, we can move the margins and give/take a few million)
Zimbabwe UN figure (2025) - 17M people
Zimbabwe 2022 census found 15.2M people, assuming a 1.90% growth rate gives 16.1 million people for 2025 (a difference of 900,000 people, or a 5.2% discrepancy)
Togo UN figure - 9.6M people
Togo 2022 census found 8,074,600 people, using 2022-2024 modest pop. growth rates that gives ~8,400,000 people for 2025 (12.5% difference)
This is just for 3 countries, all with functional statistical organizations, the list goes on and on… With failed states, the lack of statistical state capacity + baked-in previous demographic projections can add the discrepancies as much as 15 to 20 percent in some cases (Nigeria is the most extreme example, 60 million people who do not exist given the food proxies + biometric ID / digital SIM registrations)
If I had to give a final estimate, it would be 800M to 1B max for the entire continent.
