According to a new report at the Investigative Reporting Workshop, people who live in low-income areas of Washington get far less bang-for-their-buck when it comes to internet service.

John Dunbar notes that of subscribers to stand-alone broadband service in the District, wealthier ZIP codes paid four dollars more per month for service, but lower-income ZIP codes paid more than three times their wealthier counterparts per megabit, per second. Dunbar and a group of American University researchers also present some intriguing numbers comparing Verizon, Cox and Comcast and conclude that more transparency on the part of service providers is desperately needed in order to bridge the gap.

The IRW’s report also includes this fantastic interactive map, which allows readers to see how their ZIP code compares to others around the D.C. region. You can also test the speed of your internet connection by clicking here.
