evidence: The genesis of the claim appears to be a study -- "Wisconsin’s Mass Incarceration of African American Males: Workforce Challenges for 2013" -- prepared by John Pawasarat and Lois M. Quinn for the Employment and Training Institute at the University of Wisconsin-Milwaukee. The report noted that Wisconsin was the worst state in the nation for African American incarceration, at 12.8%, based on 2010 census data. That was nearly double the national average of 6.7%. [...] A 2017 Milwaukee Neighborhood News Service report said: "In 53206, the population is 94 percent black with an average age of about 29. In this, the most incarcerated ZIP code in the country, 47.5 percent of people and two-thirds of children live below the poverty line."
