OAKLAND -- The Bay Area has fewer concentrations of extreme poverty than a decade ago, according to a report released Thursday.

That may not console the people living in the Bay Area's five poorest neighborhoods. In five census tracts, four of them in the East Bay, more than 40 percent of residents live below the poverty line, according to the Brookings Institution report.

The neighborhoods are in downtown Berkeley, uptown Oakland, Alameda Point and parts of West Oakland, and San Francisco's Hunters Point.
