Do you know what an aging population (人口老龄化) is? An aging population is when there are more and more older people (60 and older) than before.In the 20th century the proportion (比例) of older people kept growing，and this will continue (持续) in the 21st century.For example，the proportion of older people was 8% in 1950 and 10% in 2000， Work seriously写作训练and it may get to 21% in 2050.By 2050，the number of older people in the world will be larger than the number of the young (under age 15) for the first time in history.
