Those findings offer a glimpse of the remarkably rich insights gleaned from the Atlas—a vast and granular body of data mapped across the United States—now available online and without charge. It builds on decades of research led by Harvard economist Raj Chetty, with support from the Robert Wood Johnson Foundation. It offers new ways to understand what drives social mobility; where significant gaps persist; and how more effective policies and practices can promote greater equity toward a Culture of Health. Most significantly, this data is openly available for use to inform localized approaches to bridge the opportunity gap.
Social Mobility Is Declining
Using data from the U.S. Census Bureau and the Internal Revenue Service (IRS), the Atlas tracks the outcomes of 20 million Americans from childhood to their mid-30s in all 70,000 census tracts with the ability to analyze findings by race, gender, and income. In the past, we could measure neighborhood wealth and poverty at a given moment, but never before could we see how early childhood experiences can influence income into adulthood.
Sadly, the new findings challenge the bedrock principle that America remains a land of opportunity for all. Two broad trends emerge. First, adjacent neighborhoods with similar household incomes and racial makeup can produce children whose adult lives veer off in very different directions. And second, in a single neighborhood, children growing up in almost identical households (in terms of income and family composition) can diverge dramatically as adults—with race being the only differing characteristic.
As we drill deeper into the Atlas data, another conclusion is inescapable: We can no longer assume that children will lead better lives than their parents, and black residents are particularly at risk for moving down the income ladder. In one Prattville, Ala., tract, for example, black children who grew up in high-income households average $19,000 in annual household earnings as adults, compared to $55,000 for white individuals from the same economic group.
Along with income, with its well-established link to health outcomes—the Atlas includes local data on educational level, housing costs, rates of employment, incarceration, and teenage births. At RWJF, we know there is a direct line from opportunity to equity to health—with access to good schools; affordable housing; safe neighborhoods; and quality health care as some of the key stepping stones. When those resources are unevenly distributed across neighborhoods—and sometimes within the same few blocks, as the Atlas illustrates—health outcomes are certain to be inequitable as well.
Data Is a Starting Point
There is much more to learn from The Opportunity Atlas, especially at the local level, where knowledge can often drive the most direct action. Chetty’s team negotiated at length with the Census Bureau and the IRS to offer open access to this vast storehouse of anonymized data. That was a highly unusual decision for scholars, because data is the coin for academic advancement, and researchers typically hold it close. Their recognition that cooperation, not competition, is the best way to mine information and improve opportunity for children across the United States is truly something to applaud.
This new tool raises as many questions as it answers. Why do low-income American Indian children in Oklahoma move into the middle class as adults in much greater numbers than the same population growing up in South Dakota? Why do children in rural Eastern Iowa have greater economic mobility than children from similar family backgrounds in urban areas—while in parts of North Carolina, the rural/urban divide is reversed? Why do Compton and Watts, both poor communities in central Los Angeles, offer such different opportunities to children who are raised there? The Atlas is only a starting point to dig deeper into these kinds of questions.
