World population hits 8 billion
全球人口达到80亿
The global population reached 8 billion on Nov 15, 2022. The number is forecast to increase in the next few decades, although at a slower pace, according to the World Population Prospects 2022 report released recently by the United Nations.
根据联合国近期发布的《世界人口展望2022》报告，2022年11月15日，全球人口总数达到80亿，这一数字在未来几十年内将持续增长，但增速预计放缓。
The global population is expected to rise to about 8.5 billion by 2030, 9.7 billion by 2050, peak at about 10.4 billion in the 2080s, and stay there until 2100, the report said.
报告说，到2030年，全球人口预计将增至约85亿左右。2050年达到97亿，本世纪80年代达到约104亿的峰值，并一直持续至2100年。
World population growth peaked at 2.1 percent between 1962 and 1965, and has since fallen sharply to less than 1 percent in 2020.
1962至1965年，世界人口年增长达到2.1%的峰值。此后急剧下降到2020年的 1%以下。
The UN predicts that global population growth could fall to about 0.5 percent by 2050 as fertility rates continue to fall.
联合国预测，由于生育率持续下降，到2050年，全球人口年增长率可能会下降到0.5%左右。
On the other hand, the average global life expectancy continues to rise, from 63.8 years in 1990 to 72.8 years in 2019, and is projected to reach 77.2 years in 2050, when 16 percent of the population will be 65 years or older.
另一方面，全球平均预期寿命持续增加，从1990年的63.8岁上升至2019年的72.8岁，到2050年预计达到77.2岁。届时，65岁以上人口占总人口比例接达16%。
Rising life expectancy combined with falling fertility rates will exacerbate global aging, lifting demand for elderly care and affecting labor markets and national pension systems.
预期寿命增加，加上生育率下降，将加剧全球人口老龄化，老年人护理需求增加，这将影响劳动力市场和国家养老金体系
Currently, China and India are the most populated countries in the world, with 1.4 billion people each.
目前，中国和印度各有超过14亿的人口，是世界上人口最多的国家。
But based on UN projections, India will surpass China for the first time in 2023 and reach 1.7 billion people by 2050.
但根据联合国的预测，印度将在2023年首次超过中国，并在2050年达到17亿。
More than half of the projected increase in the global population up to 2050 will be concentrated in eight countries: the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and the United Republic of Tanzania.
预计到2050年，全球新增人口中超过一半将集中在刚果(金)、埃及、埃塞俄比亚、印度、尼日利亚、巴基斯坦、菲律宾和坦桑尼亚8个国家。
