2.摘抄:
"The urban world is facing a double demographic hit on economic growth. Between 2000 and 2012, an expanding population drove nearly 60 percent of economic growth in the world’s large cities, but those days of easy urban growth are over. First, global population growth is slowing due to declining fertility rates and an aging population. Second, the pace of rural-to-urban migration is waning in many regions"
3.感想:
一些有趣的事实
(1) 全口人口增长放缓+农村向城市迁移人口减少
(2)用美国,西欧,日本三个面临人口老龄化危机的国家做比较,发现美国的人口结构是最健康的,这主要归功于它的移民政策.日本最惨,除了东京等超大城市持续有人口流入,40%的小型城市出现人口倒退和生育年龄妇女数量急剧下降.
所以,川普的反移民政策会对美国的人口结构有什么影响呢? 我们拭目以待!
