A new study from Harvard economists Raj Chetty and Nathaniel Hendren seeks to quantify the financial impact of where America's children are brought up. More specifically, Chetty and Hendren measure "the percentage earnings gain from growing up in each county [in America] relative to an average place for children in low-income families."
The goal of the study (and its predecessors) is to determine the most effective way to imporove economic outcomes for low-income children. Here, the researchers "focus on families who moved across areas to study how neighborhoods affect upward mobility." Unsurprisingly, Chetty and Hendren "find that every year of exposure to a better environment improves a child’s chances of success." Interestingly, the economists have actually quantified the improvement in order to "estimates of the causal effect of each county in America on upward mobility."
The map below, from NY Times, shows "how much extra money a county causes children in poor families to make" compared to national averages for low-income households:

Raj Chetty and Nathaniel Hendren [have had] huge consequences on how we think about poverty and mobility in the United States. The pair, economists at Harvard, have long been known for their work on income mobility, but the latest findings go further. Now, the researchers are no longer confined to talking about which counties merely correlate well with income mobility; new data suggests some places actually cause it.
Across the country, the researchers found five factors associated with strong upward mobility: less segregation by income and race, lower levels of income inequality, better schools, lower rates of violent crime, and a larger share of two-parent households. In general, the effects of place are sharper for boys than for girls, and for lower-income children than for rich.
“The broader lesson of our analysis,” Mr. Chetty and Mr. Hendren write, “is that social mobility should be tackled at a local level.”
