The Population Reference Bureau (PRB) ranking list is based on the data of the 2024 World Population Data Sheet [6] published online. The PRB [7] is a private, nonprofit organization which informs people around the world about population, health and the environment for research or academic purposes. It was founded in 1929.
According to UN estimates, the population of Africa may reach 2.49 billion by 2050 (about 26% of the world's total) and 4.28 billion by 2100 (about 39% of the world's total). [13] The number of babies born in Africa compared to the rest of the world is expected to reach approximately 37% in the year 2050. [14]
A 2023 map of countries by fertility rate. Blue indicates negative fertility rates. Red indicates positive rates. The total fertility rate (TFR) of a population is the average number of children that are born to a woman over her lifetime, if they were to experience the exact current age-specific fertility rates (ASFRs) through their lifetime, and they were to live from birth until the end of ...
This increase in number of babies born in Africa compared to the rest of the world is expected to reach approximately 37% in the year 2050; while in 1990 sub-Saharan Africa accounted for only 16% of the world's births. [220] The total fertility rate (children per woman) for Sub-Saharan Africa is 4.7 as of 2018, the highest in the world. [221]
The percentage of children living in severe food poverty in West and Central Africa fell from 42% to 32% over the last decade, it said, noting advances including diversified crops and performance ...
Based on this, the UN projected that the world population, 8 billion as of 2023, would peak around the year 2086 at about 10.4 billion, and then start a slow decline, assuming a continuing decrease in the global average fertility rate from 2.5 births per woman during the 2015–2020 period to 1.8 by the year 2100 (the medium-variant projection).
As of 2009, the average birth rate (unclear whether this is the weighted average rate per country [with each country getting a weight of 1], or the unweighted average of the entire world population) for the whole world is 19.95 per year per 1000 total population, a 0.48% decline from 2003's world birth rate of 20.43 per 1000 total population.
The 2024 average of 17 births per 1,000 total population equates to approximately 4.3 births per second or about 260 births per minute for the world. On average, two people in the world die every second or about 121 per minute.
