聯合國報告 全球人口2050年將達98億

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.

聯合國日前表示，儘管世界各地的生育率幾乎都有所下降，但世界人口仍將在2030年達到86億，到2050年達到98億。

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年修訂版顯示，在發展中國家相對較高的生育率的推動下，世界人口從去年的74億增至目前的至少76億。

"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.

撰寫報告的聯合國經濟和社會事務部表示：“世界人口每年約增加8300萬。按此速度，即使假設生育率將繼續下降，人口規模的上升趨勢預計仍將持續。”

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.

報告指出，生育率降低正導致人口老齡化，60歲或以上人口數量到2050年預計將增加一倍以上，到2100年增加兩倍，從目前的9.62億增至31億。

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.

該報告預測，到2024年，目前以13億人口位居第二人口大國的印度的人口將超越中國的14億人口。

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

到2050年，目前的第七人口大國尼日利亞將取代美國成爲第三人口大國。
