Sharp rise in San Francisco's black jail population

As San Francisco's population of African American residents has decreased in recent years, the population of black men and women locked up in the San Francisco County Jail has increased dramatically. More than 60% of all prisoners are African American, according to a survey of the city jail's population. And of the 282 female prisoners, 67% are black. A similar study in 1996 found that half of the jail population was African American. A 2005 study put the number at 53%. In contrast, 6.7% of San Francisco residents are black - a number that has been in steady decline, according to the U.S. Census Bureau.
