2014 – District 5: Tube Charts Reveal Decline in Violence

California-based artist Loren Madsen, a long-time data sculptor (see our 1995 entry and our interview with him), created an outdoor sculpture where steel tubes show falling crime rates across eight crime categories over 30 years. The sculpture stands in front of a police station and jail in Chicago City.
