In 2019, 125 people in Stockton, California, started receiving $500 a month, no strings attached. The privately funded program, known as the Stockton Economic Empowerment Demonstration (SEED), was designed not only to boost a handful of low-income residents in this struggling city of 300,000 in the Central Valley. It was a rigorous, randomized-control study, meant to evaluate whether, and how, doling out a localized basic income could work, and what happens to those who receive free money.
