When Marketplace’s Wealth and Poverty team started reporting on welfare reform almost a year ago, our goal was to follow the money. We wanted to know how federal welfare dollars were spent and to what impact. The answers involved nine months of digging deep into Excel spreadsheets, government contracts and state budgets, and the result was season one of our new podcast The Uncertain Hour. We not only learned about where the money went, but the effect this reform, enacted in 1996, has had on our country.Today—20 years after welfare reform—what do we know about welfare?We know welfare rolls dropped dramatically (from 4.4 million families in 1996 to 1.6 million in 2014).

In the years since, she never returned to welfare. But she did sell blood plasma to make ends meet. And she does collect cans to redeem for cash.Larry Townsend, the “magic bureaucrat,” who in some ways created the national blueprint for welfare reform, starting with a pilot program in his county welfare department in Riverside, California.And Elana Gamble who was a single mother attending community college when welfare ...
