An FBI report shows crime spiked noticeably in most Bay Area cities in 2012.
Incidents of rape, murder, robbery and assaults all rose throughout the region, according to the Bay Area News Group.
The rise is an "about-face" from a longtime trend of declining crime numbers, according to the report.
Crime increased nationwide by 1.2 percent in 2012, after dropping by 4 percent, 6 percent and 4.4 percent in the three years prior, respectively.
Oakland, which has had a longstanding police staffing problem, experienced the starkest increase in crime. Violent crime in the city spiked nearly 20 percent in 2012, with robberies up 29 percent.
The Bay Area News Group recently crowned Oakland "the robbery capital of the U.S.," a title seemingly backed up by the FBI data.
In San Jose, violent crime spiked 10.6 percent, with the number of rapes, murders, and robberies all on the rise.
However, not all Bay Area communities are beset by criminals.
In Concord, Contra Costa County's largest city, there were no homicides in 2012, compared with seven in 2011.
