开始段 - 改写题目+总结
The line graph illustrates the percentage of the population aged 18–34 between 1978 and 2011, while the two pie charts compare the distribution of this age group across urban areas, towns, and rural areas in 1978 and 2011. Overall, the percentage of young adults in the population rose slightly during the first half of the period, before falling to a lower level by 2011. At the same time, these individuals became increasingly concentrated in urban areas, while the share living in rural regions dropped dramatically.
第一段 - 分析人口占比变化
In 1978, people aged 18–34 made up about 35% of the population. This figure climbed gradually to reach a peak of approximately 38% in 1992. However, after the early 1990s, the trend reversed, and the proportion of young adults declined steadily to around 30% by 2011, which was noticeably below the initial level.
第二段 - 居住地占比
Regarding geographical distribution, in 1978, a majority (55%) of this age bracket lived in cities, compared to 25% in rural areas and 20% in towns. By 2011, the urban share had grown to 65%, whereas the rural segment had plummeted to just 5%. Meanwhile, the proportion of 18–34-year-olds residing in towns increased to 30%.
