That’s up from a pandemic low of 70.9 in 2021 and higher than the pre-pandemic 72.4 five years earlier. Global life expectancy is projected to reach 81.7 years in 2100.
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 ...
Countries need a fertility rate of about 2.1 kids per family to maintain a stable population. But two-thirds of the world's population already lives in countries where fertility is below this so ...
To maintain stable population numbers, countries need a total fertility rate of 2.1 children per woman, a number called the replacement level. When the fertility rate falls below the replacement ...
The following list sorts countries and dependent territories by their net reproduction rate.The net reproduction rate (R 0) is the number of surviving daughters per woman and an important indicator of the population's reproductive rate.
South Korea has the world's lowest fertility rate, at just 0.78 births per woman as of 2022.It's likely to get even worse, with Statistics Korea, the country's official statistics bureau ...
A map of when European fertility rates fell below replacement levels Map of countries by crude birth rate Map of countries by total fertility rate. Sub-replacement fertility is a total fertility rate (TFR) that (if sustained) leads to each new generation being less populous than the older, previous one in a given area.
