This report is no surprise to me. Our criminal justice system long has attacked the poor and those of color. See many articles under “Race”.

Open the Story to see the charts, like the one: “Incarceration rate of men between 28 and 34, by parents income”!

 

Men who grew up in the poorest 10 percent of American families are 20 times as likely to be imprisoned by their early 30s than men from the richest 10 percent of families, according to a new Brookings Institution analysis of the drivers of incarceration.

“We estimate that almost one in ten boys born to families in the lowest income decile are incarcerated at age 30, and they make up about 27 percent of prisoners that age,” the study’s authors, Adam Looney and Nicholas Turner, concluded.

By contrast, fewer than half of 1 percent of men from the richest 10 percent of families were imprisoned on any given day in their early 30s.

That stark relationship — between childhood family income and adult incarceration — underscores how much the environments children grow up in can shape their life trajectories.

To produce their analysis, Looney and Turner collected Internal Revenue Service tax returns for 2.9 million incarcerated individuals. For a subset of about 500,000 of those inmates, they were able to link incarcerated individuals to their parents’ income tax returns, providing snapshots of where the future inmates were born and how much money their families made at the time of their birth.

While the incarceration rates for girls were much lower, the data showed a similarly sharp incarceration gradient running along the income spectrum.

They also found that children from single-parent families were about twice as likely to end up incarcerated as the children of married parents, regardless of family income.

Children of poor families are thus heavily overrepresented in the prison population. Among the cohort of prisoners age 28 to 34 the authors examined, the bottom 5 percent of families, by income, produced about 30 percent of the inmates. The bottom 20 percent of households produced nearly half the inmates, while the bottom 50 percent of families accounted for over 82 percent of inmates.

Incorporating family structure into the analysis, the study found that “boys from single-parent families in the bottom 10 percent of the income distribution — a group that makes up only 3.7 percent of the overall population” — accounted for 20 percent of all prisoners in 2012. Conversely, boys with married parents who grew up in the top 50 percent of households accounted for 46 percent of all boys but only 14 percent of men in prison.

 

“The neighborhoods with high incarceration rates are predominantly black, or are otherwise nonwhite, have child poverty rates that are two to three times the national average, and have male unemployment rates substantially higher than the rest of the country,” Looney and Turner found.

“Poor African American and Native American boys living in segregated communities of concentrated poverty are highly unlikely to experience anything but unemployment or incarceration or both,” wrote the Brookings Institution’s Camille Busette in an accompanying commentary. “If we add to this the fact that police disproportionally kill African American and Native American men, it is clear that the level of exclusion faced by these men is staggering.”

Other research has shown that one way out of the cycle of poverty, violence and incarceration is to get out — literally. A 2015 study by Raj Chetty and colleagues found that “moving to a lower-poverty neighborhood significantly improves college attendance rates and earnings for children who were young (below age 13) when their families moved.”
