据联合国《世界人口展望2022》报告预计，全球人口在昨天达到80亿，这是人类发展的一个里程碑。
On Nov 15, 2022, the world's population is projected to reach 8 billion people, a milestone in human development.
联合国网站显示，全球人口从70亿增长到80亿花了约12年时间，而到2037年达到90亿将需要大约15年的时间，这表明全球人口的总体增长速度正在放缓。
While it took the global population 12 years to grow from 7 to 8 billion, it will take approximately 15 years — until 2037 — for it to reach 9 billion, a sign that the overall growth rate of the global population is slowing.
The global population will start to peak at around 10.4 billion people in the 2080s and remain at that level until 2100.
The University of Washington report estimated that the global population would peak in 2064 at 9.7 billion before declining to 8.8 billion in 2100.
Currently, China and India are joint-most populated countries in the world, with 1.4 billion people each. But based on UN projections, India will surpass China for the first time in 2023.
联合国预计，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。
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.
是的，但增速正在放缓。世界人口在1962-1965年期间的增长率为每年2.1%，此后增速急剧下降，2020年不到1%。到2050年，全球人口年增长率可能会下降到0.5%左右。
全球的平均预期寿命持续增加。2019年，全球平均预期寿命为72.8岁，比1990年时增加了9岁；到2050年，预计平均预期寿命将达到77.2岁。
联合国秘书长古特雷斯在《80亿人口，一个人类》中表示，人类大家庭在日益壮大的同时，也面临着日益严重的不平等问题。如果不解决这些问题，世界上将充满紧张和不信任、危机和冲突。
As our human family grows larger, it is also growing more divided. Unless we bridge the yawning chasm between the global haves and have-nots, we are setting ourselves up for an 8-billion-strong world filled with tensions and mistrust, crisis and conflict.
