The number of young people in the country will fall by around 30 million by 2022 compared to the figure in 2017, according to a research conducted by the Chinese Academy of Social Sciences.

中国社会科学院组织的一项研究显示，到2022年，我国青年人口将较2017年减少约3000万人。

The research based on data from the sixth national population census¹ of 2010 showed that China had 548 million people aged between 18 and 44, but the figure will be only 518 million in 2022.

根据这项基于2010年第六次全国人口普查数据的研究，我国18至44岁人口数量为5.48亿，但到2022年这一数字将缩减至5.18亿。

The population aged between 18 and 35 will also decline from 366 million in 2017 to 344 million in 2022.

到2022年，18至35岁人口数量也将从2017年的3.66亿下降至3.44亿。

Li Jianxin, a sociologist² from Peking University, carried out a separate research based on the UN's "World Population Prospects³: The 2010 Revision" and arrived at similar results.

北京大学社会学家李建新根据联合国的《世界人口展望-2010年修订版》进行了一项单独的研究，并得出了类似的结果。

The population aged between 15 and 24 in China will decline from 225 million in 2010 to 178 million in 2020, down 47 million in 10 years, Li said.

李建新称，我国15至24岁的人口数量将从2010年的2.25亿下降至2020年的1.78亿，在10年内减少了4700万。

The group will account for 18 percent of the total population in 2020, down from 23.17 percent in 2010, much lower than the US' 19.91 percent and India's 26.33 percent then.

到2020年，这一年龄段人群占总人口的比例则将从2010年的23.17%下降到2020年的18%，低于美国的19.91%和印度的26.33%。

He said authorities should relax the limits on childbirth and encourage the childbearing population to have more babies, and meanwhile reduce the costs of parenting and the burden for supporting the elderly.

他表示，当局应该放宽生育限制，鼓励生育年龄人口多生孩子，同时减少抚养孩子的费用和赡养老人的负担。
