The Opportunity Atlas followed millions of children to adulthood and recorded who was incarcerated. For boys born to poor families, the odds rise with the deprivation of the block they grew up on — but the sharpest divide is not deprivation. On the very same streets, a Black child from a poor family is locked up at two and a half times the rate of a white one.
The Opportunity Atlas links twenty million Americans to the census tract where they were children and to administrative records of how their lives turned out — including whether they were incarcerated on April 1, 2010. Read as a map, it shows where a poor childhood becomes a criminal record.
It is the dark mirror of the mobility maps elsewhere in this project. Where those ask which neighborhoods lift poor children up, this one asks which neighborhoods route them into a cell — and finds that the answer depends less on how poor the place is than on the color of the child growing up in it.
Incarceration of poor children does rise with neighborhood deprivation — from about 1.1% in the least-deprived tracts to 3.2% in the most, a near-tripling. But for this project the slope is unusually shallow: the correlation with deprivation is only 0.26, far weaker than deprivation's grip on life expectancy or health. Incarceration tracks something the deprivation index does not fully capture — and the next chart names it.
Split the poor children by race and hold the neighborhood constant. In the 36,000 tracts where both groups can be measured, Black children from poor families are incarcerated at 5.2% versus 1.9% for white children from equally poor families on the same blocks. The gap is not a deprivation effect: it is wide in the most advantaged tracts (3.7% vs 1.0%) and wide in the most deprived (6.2% vs 2.6%). Two children, one street, two ladders — exactly as the income-mobility maps found, but steeper.
One dot per tract: the Black rate on the vertical axis, the white rate on the horizontal, for poor children raised in the same place. If race made no difference, the cloud would sit on the diagonal. Instead 73% of tracts lie above it — the Black rate exceeds the white rate in nearly three of every four shared neighborhoods, and rarely by a little.
The book's recurring test is whether a gap survives the map. Most do not: hold the neighborhood constant and the gap shrinks, because so much of inequality is geography wearing a demographic disguise. This one survives. The same-tract Black–white incarceration gap is wide at every level of deprivation, which means it is not the neighborhood doing the sorting — it is something carried across neighborhoods: differential policing, school discipline, and the long reach of a criminal-justice system that meets the same poor childhood with very different force depending on the child.
Incarceration is also the rare outcome that forecloses the others. A childhood that ends in a cell does not appear in the income-mobility success stories; the two outcomes correlate at −0.44. The places and the children that this map marks are, disproportionately, the ones missing from the hopeful maps.
