The SF Appeal has an article and google map that plots where the 2011 homicides in San Francisco have occurred. As you might (or might not, who knows) expect, the most homicides have occurred in the rougher neighborhoods of San Francisco, with the tenderloin and mid-market area having numerous homicides, as well as the southern end of Potrero Hill and Bernal Heights (where public housing projects are located in both neighborhoods), with the Bayview and Ingleside also clocking in with multiple fatalities.
You can click on the above map to open it in a new window and get details on each of the homicides.
As for where the homicides aren’t? As you can see the west side of the city is a blank slate, and while some accused the west side of San Francisco as being the part of the city where nothing happens. Perhaps in this case that nothing is a very good thing? District 2 (Sunset/Parkside), and d1 (Richmond) are all homicide-free year to date, and most of d4 is as well (west of twin peaks, including areas like West Portal, Forest Hill, and St. Francis Wood) the exception being the homicide that occurred in Diamond Heights earlier in the year.
You may also recall that I blogged recently about the trulia insight post that visualized what time was “prime-time” for crime in San Francisco (and 24 other cities), but I’d have to say in the overwhelming majority of San Francisco (and these neighborhoods as well) you are very safe during daylight hours. Which isn’t to say that some horrible and unfortunate crimes do occur during the day. There are a variety of online crime statistic resources available now. What resources do you use when house hunting, and what types of crimes are of most concern to you?
