Growing concerns about wealth inequality and the expanding racial wealth gap have in recent years become central to the debate over whether our nation is on a sustainable economic path. This report provides critical new information about what has fueled the racial wealth gap and points to policy approaches that will set our country in a more equitable and prosperous direction.Looking at the same set of families over a 25-year period (1984-2009), our research offers key insight into how policy and the real, lived-experience of families in schools, communities, and at work affect wealth accumulation. Tracing the same households during that period, the total wealth gap between white and African-American families nearly triples, increasing from 85,000in1984to236,500 in 2009. To discover the major drivers behind this dramatic $152,000 increase, we tested a wide range of possible explanations, including family, labor market, and wealth characteristics. This allowed us, for the first time, to identify the primary forces behind the racial wealth gap. Our analysis found little evidence to support common perceptions about what underlies the ability to build wealth, including the notion that personal attributes and behavioral choices are key pieces of the equation. Instead, the evidence points to policy and the configuration of both opportunities and barriers in workplaces, schools, and communities that reinforce deeply entrenched racial dynamics in how wealth is accumulated and that continue to permeate the most important spheres of everyday life
