很多人说我没结婚不生小孩是因为我没钱
如果我有钱 我一定生很多
不过现实刚好相反 根据统计是越穷生越多
以美国为例
https://www.statista.com/statistics/241530/birth-rate-by-family-income-in-the-us/
"the birth rate in the United States was highest in families that had under
10,000 U.S. dollars in income per year, at 63.14 births per 1,000 women. As
the income scale increases, the birth rate decreases, with families making
200,000 U.S. dollars or more per year having the lowest birth rate,"
在美国生育率跟家庭收入呈反比
As the income scale increases, the birth rate decreases
不只在美国 世界各地都这样
Income and high birth rates are strongly linked, not just in the United
States, but around the world.
有人说是m型化
不过依照那一张统计图表 并没有显示m型化 而是负相关
