The community in which a person grows up exerts a big influence on his/her life-course. D’uh. Only now we have a big social science study to validate this common belief. Growing up in a low-income black area reduces one’s chances of rising into the middle class, even if the person is white.
Some areas are dead-ends for low-income people. The old cotton South, Southern California, and much of the Rust Belt are bad places to be stuck.
Where are the places with the biggest positive impact on the earnings of low-income people? Places with lots of Scandinavians or Mormons: southern Minnesota, northern Iowa, Utah, adjacent parts of Wyoming, and southeastern Idaho. What distinguishes areas favorable to social mobility from places unfavorable to social mobility? The quality of the public schools, the share of two-parent families, the degree of social engagement by the community (functioning civic and religious groups), and the integration of different income groups in a single community.
Of course, the study may actually reveal the character of the people who go, as much as the character of the places to which those people go. Again, d’uh. Children who moved from a low-income area to a higher-income area were later in life, less likely to become single parents, more likely to go to college, and earned more money. Moreover, the places where poor people cluster are full of poor people. The schools are poor, there is a lot of pathological behavior, and it isn’t very safe. Parents who move from a lower-income place to a better-income place do their children an immense service. Still, they have to pay a cost.
However, the study revealed several disparities. One is between older and younger siblings in the same families. The sooner a kid gets out, the better for their life prospects; the later a kid gets out, the worse for their life prospects. Getting a kid out before age 9 or 10 offers the best hope. Chances decline rapidly after that age. A second disparity is between the sexes. Low-income women who grow up in higher income areas earn about 25 percent more than low-income women who grow up in low-income areas. Low-income men who grow up in a higher-income area earn about 30 percent more than men who grow up in a low-income area. What was not reported was the comparative chances of being employed or unemployed.
The same study found that “commuting time has emerged as the single strongest factor in the odds of escaping poverty.” The longer is the commute, the lower is the chance of improving one’s life. Basically, there aren’t any jobs in the places where poor people live. To get a job, someone has to travel. One of the big problems is that public transportation is not equally distributed across communities. In a lot of middle-class places, everyone has a car so no one cares about public transportation. If someone who is poor wants to live in one of these communities, they need to get a car. Aye, there’s the rub.
Still, what causes higher-income areas to be better than low-income areas? Sure, “they have more money.” Why do they have more money? Because they’ve always had more money, so they have better schools, two-parent families, and kids who go to college? Or because there is a culture that values marriage, family, education, and civic engagement? Which of these factors can be addressed by public policy? Which are matters of “personal responsibility”?
