China's population will peak in 2029 at 1.44 billion before beginning a period of "unstoppable" decline, a government report says.

一份政府报告指出，我国人口将在2029年达到14.4亿，然后开始进入“势不可挡”的衰退期。

The China Academy of Social Sciences (CASS) study says the country must implement¹ policies to handle a smaller workforce² and an older population.

中国社会科学院的研究表明，中国必须实施政策，以应对劳动力减少及老年化。

Both changes combined could cause "very unfavourable social and economic consequences", the report says.

该报告称，这两项变化相结合可能会导致“非常不利的社会和经济后果”。

Latest UN estimates say China has a population of 1.41 billion. In 2015 the world's most populous³ country ended its one-child policy in a bid to tackle the problems.

联合国最新估计称，中国人口为14.1亿。2015年，这个世界上人口最多的国家终止了独生子女政策，以解决这些问题。

绿皮书指出 我国人口负增长时代即将到来

The study appears in CASS's Green Book of Population and Labour.

该研究发表在中国社会科学院的《人口与劳动绿皮书》中。

Working population numbers were now stagnating⁴, it said, with a low fertility rate set to cause further issues.

该绿皮书指出，劳动力人口数量目前停滞不前，低生育率将导致进一步的问题。

By the middle of the century, China's population is expected to drop to 1.36 billion -- a fall in the labour force of close to 200 million.

到本世纪中叶，中国的人口预计将下降到13.6亿，其中劳动力人口将下降接近2亿。

If fertility rates stay low, the population could drop as low as 1.17 billion by 2065.

如果生育率保持低水平，到2065年人口可能会下降到11.7亿。
