While the global population is still increasing in absolute numbers, population growth peaked decades ago. In the chart, we see the global population growth rate per year. This is based on historical UN estimates and its medium projection to 2100.

2023年6月1日 · The fastest doubling of the world population happened between 1950 and 1987: from 2.5 to 5 billion people in just 37 years — the population doubled within a little more than one generation. This period was marked by a peak population growth of 2.1% in 1962. Since then, population growth has been slowing, and the doubling time alongside it.

2024年7月11日 · This year’s edition brings this peak forward slightly to 2084, with the population topping at just under 10.3 billion. The chart below compares the two revisions. This isn’t the first time the projected peak has been pulled earlier. According to its 2019 edition, the global population would reach 10.9 billion by 2100 and keep growing. The ...

World Population Prospects 2024 is the 28th edition of the official estimates and projections of the global population that have been published by the United Nations since 1951. The estimates are based on all available sources of data on population size and levels of fertility, mortality and international migration for 237 countries or areas.

2023年3月18日 · As population growth continues to decline, the curve representing the world population is getting less and less steep. Towards the end of the century, the UN expects the global population to reach its peak at around 10.4 billion.

2024年7月15日 · Average exponential rate of growth of the population over a given period. It is calculated as ln(P2/P1) where P1 and P2 are the populations on subsequent years. Available from 1700 to 2100, based on data and estimates from different sources.

Historical national accounts estimates of the share of the world's population living on less than $5 per day, by region; How do UN Population projections compare to the previous revision? Natural population growth with UN projections; Natural population growth rate vs. child mortality rate; Natural population growth rate vs. median age

2024年11月25日 · This remarkable increase is due to improved living standards, like better nutrition and sanitation, and advances in healthcare, such as antibiotics and vaccines. While large declines in child mortality have been crucial, they have not been the only reason for the increase in life expectancy; it has increased across all ages .

2019年6月1日 · If these changes happened at the same time, the size of the population would not increase. What is crucial is the timing at which mortality and fertility change. The model that explains why countries go through a period of rapid population growth is …
