NEW DELHI, July 11 (Reuters) - India is set to surpass China as the world's most populous country in 2023, with each counting more than 1.4 billion residents this year, a United Nations report said on Monday, warning that high fertility would challenge economic growth.
The world's population, estimated to reach 8 billion by Nov. 15 this year, could grow to 8.5 billion in 2030, and 10.4 billion in 2100, as the pace of mortality slows, said the report released on World Population Day.
India's population was 1.21 billion in 2011, according to the domestic census, which is conducted once a decade. The government had deferred the 2021 census due to the COVID-19 pandemic.

联合国周一发布的一份报告警告称,2023年,印度将超越中国,成为世界上人口最多的国家。今年,印度人口即将突破14亿,高生育率将为该国的经济增长带来挑战。
世界人口日发布的这份报告称,随着死亡率的降低,预计到今年11月15日,世界人口就将达到80亿,到2030年可能突破85亿,2100年则可能达到104亿。
根据印度十年一次的国内人口普查,2011年印度人口为12.1亿。由于新冠疫情的爆发,印度政府推迟了2021年的人口普查。

In 2021, the average fertility of the world’s population stood at 2.3 births per woman over a lifetime, having fallen from about 5 births in 1950. Global fertility is projected to decline further to 2.1 births per woman by 2050.
"This is an occasion to celebrate our diversity, recognize our common humanity, and marvel at advancements in health that have extended lifespans and dramatically reduced maternal and child mortality rates," UN Secretary-General António Guterres said in a statement.
Still, a growing population was a reminder of a shared responsibility of care for the planet and to "reflect on where we still fall short of our commitments to one another," he said.

2021年,世界人口的平均生育率为每名妇女一生生育2.3个孩子。在1950年这一数字为5个。而预计到2050年时,全球生育率将进一步下降到每名妇女生育2.1个孩子。
联合国秘书长安东尼奥·古特雷斯(António Guterres)在一份声明中说:“这是一个庆祝我们的多样性、承认我们的共同人性、惊叹人类健康进步的机会,这些进步延长了寿命,显著降低了孕产妇和儿童的死亡率。”
尽管如此,不断增长的人口也提醒我们要共同承担起保护地球的责任,并“反思我们在哪些方面仍然没有履行对彼此的承诺,”他说。

Referring to an earlier World Health Organisation report- estimating about 14.9 million deaths relating to the COVID-19 pandemic between January 2020 and December 2021, the UN report said global life expectancy at birth fell to 71 years in 2021 from 72.8 years in 2019, mostly due to the pandemic.
The United Nations said more than half of the projected increase in the global population up to 2050 will be concentrated in eight countries - Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and the United Republic of Tanzania.
However, the population of 61 countries is projected to decrease by 1% or more between 2022 and 2050, driven by a fall in fertility.

根据世界卫生组织早些时候的一份报告——2020年1月至2021年12月期间,与新冠大流行相关的死亡人数约为1490万。联合国报告称,主要由于新冠大流行造成的影响,全球人口出生时预期寿命从2019年的72.8岁,下降到了2021年的71岁。
联合国报告还指出,到2050年,预计全球人口增长的一半以上将集中在八个国家——刚果、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。
然而,由于生育率下降,预计2022年到2050年间,全球有61个国家将出现至少1%的人口减少。
