联合国报告 全球人口2050年将达98亿

The United Nations said that the world Population is expected to reach 8.6 billion in 2030, and to hit 9.8 billion by 2050, despite nearly universal lower fertility rates.

联合国日前表示，尽管世界各地的生育率几乎都有所下降，但世界人口仍将在2030年达到86亿，到2050年达到98亿。

The world population is now at least 7.6 billion, up from 7.4 billion last year, spurred by the relatively high levels of fertility in developing countries, revealed World Population Prospects: The 2017 Revision.

《世界人口展望》2017年修订版显示，在发展中国家相对较高的生育率的推动下，世界人口从去年的74亿增至目前的至少76亿。

"With roughly 83 million people being added to the world's population every year, the upward trend in population size is expected to continue, even assuming that fertility levels will continue to decline," said the UN Department of Economic and Social Affairs, which produces the report.

撰写报告的联合国经济和社会事务部表示：“世界人口每年约增加8300万。按此速度，即使假设生育率将继续下降，人口规模的上升趋势预计仍将持续。”

The lower fertility rates are resulting in an ageing population, with the number of people aged 60 or over expected to more than double by 2050 and triple by 2100, from the current 962 million to 3.1 billion, the report noted.

报告指出，生育率降低正导致人口老龄化，60岁或以上人口数量到2050年预计将增加一倍以上，到2100年增加两倍，从目前的9.62亿增至31亿。

The population of India, which currently ranks as the second most populous country with 1.3 billion inhabitants, will surpass China's 1.4 billion citizens, by 2024, the report predicted.

该报告预测，到2024年，目前以13亿人口位居第二人口大国的印度的人口将超越中国的14亿人口。

By 2050, the third most populous country will be Nigeria, which currently ranks seventh and is poised to replace the US.

到2050年，目前的第七人口大国尼日利亚将取代美国成为第三人口大国。
