Hi freinds. How are you all. I hope you all will be fine. Here I want to tell about the current population rate of the world.

Every two years, the United Nations makes projections for future population growth. Its latest medium projection – the most likely scenario – is a population of  9.7bn in 2050  and  10.4bn in 2100 . Because many factors affect population growth, it makes a range of projections depending on different assumptions. Within its 95% certainty range, the difference in population in 2100 from the highest to lowest projection is 3.5bn people – almost half the population we have today.

The dotted lines on the graph above shows the UN's projected population if, on average, every other family had one fewer child or one more child than in the median projection ('low fertility and “high fertility” scenarios).

This shows the enormous difference in total numbers that arise from just very small variations in family size. If we can achieve that modest reduction in number of children born, we will have more than 3bn people fewer by 2100 – a lower population than we have today .

WHERE POPULATION GROWTH WILL OCCUR

• Eight countries will make up over half the projected total population increase by 2050: India, Nigeria, Pakistan, the Democratic Republic of the Congo, Ethiopia, Tanzania, the Philippines and Egypt.
• India is expected to overtake China as the world's most populous country next year (2023), when China's population is expected to start declining.
• 61 countries are projected to experience a population reduction by 2050.

Rapid population growth and its causes continue to pose a major impediment to achieving the  Sustainable Developments goals , in particular eradicating hunger and poverty, achieving gender equality, and improving health and education. Poverty is also a significant driver and predictor of population grow. in the UN's designated Least Developed Countries is projected to rise from just over 1bn in 2020 to 1.76bn in 2050.

我希望你们都好。我来这里是要告诉你一些关于世界最新人口的事情。
大约公元前 8000 年，世界人口约为 500 万。在直到公元 1 年的 8,000 年期间，它增长到 2 亿（有些人估计为 3 亿甚至 600，这表明对早期历史时期的人口估计可能有多么不精确），每年的增长率不到 0.05%。

工业革命发生了巨大的变化：虽然人类历史一直到 1800 年左右世界人口才达到 10 亿，但仅用了 130 年（1930 年）就实现了第二个十亿，在 30 年（1960 年）中实现了第三个十亿。 ，15 年（1974 年）达到第 4 个十亿，仅 13 年（1987 年）达到第 5 个十亿。

仅在 20 世纪，世界人口就从 16.5 亿增长到 60 亿。
1970 年，世界上的人口大约是现在的一半。
