Good morning, Washington. What accounts for Washington’s deepest divisions? A new poll conducted by the Washington Post and the Kaiser Family Foundation shows that it isn’t race — socioeconomic class is the biggest source of division in the District. The Post’s poll also found that many higher-income blacks have more in common with white residents than they do with lower-income blacks, and slightly more black residents are participating in the local government process than white residents. Of course, there are certainly divisions along racial lines to be found: for example, many more black residents believe that the District’s declining black population “has changed the culture” of the city, and white residents feel more financially secure in the District than black counterparts. You can read all findings from the poll here, or check out the Post’s infographic.

Violent Sunday In D.C.: Last night, multiple suspects were arrested for a series of armed robberies around the Fourth and Fifth Districts during which one person was shot. This morning, MPD is also investigating a homicide which occurred on the 1300 block of Levis Street NE last night — authorities do not currently have any suspects or motive, but reports are that the victim, in his 60s, was stabbed and may have been bound with duct tape. Another man was also stabbed to death on the Douglass Place SE yesterday.

Crime Stats Show Increase in Rape: There’s always a battle to be had over crime statistics in the District of Columbia — but regardless of whether you prefer to use federal stats or the Metropolitan Police Department’s, the Examiner reports that the number of rapes inside D.C. has increased over 2010. D.C. Councilmember Phil Mendelson told the paper that “it’s hard to explain the cause of the increase,” since “historically, the crime is underreported.”

Briefly Noted: It’s the last day of school in D.C….Get ready for another heat wave…Meet Metro’s union tonight…Life expectancy gap between between District blacks and whites declining…Man pleads guilty in NE nightclub stabbing…Local CEOs: still rich…MoCo hasn’t audited its employee expenses for three years…Don’t forget to properly dispose of that used charcoal, folks.

This Day in DCist: Last year, the Capitol was getting a fresh coat of paint and the city’s police tried to connect with the kids; in 2009, it was revealed that a suspect in a shooting at the Columbia Heights Metro station was an intern in Councilmember Jim Graham’s office and we reviewed the troubling tenure of former Washington Suburban Sanitary Commission commissioner Juanita Miller.
