Oakland's project is significant because it is one of the largest efforts in the U.S. so far, targeting up to 600 families. And it is the first program to limit participation strictly to Black, Indigenous and people of color communities.

The reason: White households in Oakland on average make about three times as much annually than black households, according to the Oakland Equity Index. It's also a nod to the legacy of the Black Panther Party, the political movement that was founded in Oakland in the 1960s.
