The Washington Post releases an impressive piece of datajournalism which underlines how some major US cities are struggling to deal with criminal homicides. The Post gathered data from various public records (there was no single standardized dataset!) and mapped more than 50.000 murders in order to compare arrest rates block by block.
The result is a bold map interactive which highlights so-called “pockets of impunity” — especially when victims come from a minority group — and invites readers to explore the situation of their own city. The data is pretty understandable by anyone, and it’s also nice to see a full disclosure of the Post’s methodology.
Of course, this special report is also complemented by some field reporting. This article brings readers on the ground in cities like Chicago and Philadelphia, while re-using static snapshots from the data investigation.
