evidence: Iowa’s Black to white prison ratio is no longer the worst in the nation, as it was in 2007. According to the report released by The Sentencing Project, Iowa’s disproportionate rate of incarcerating Black residents now ranks seventh in the country. [...] According to the latest analysis, Black Iowans are incarcerated at 9.3 times the rate of white Iowans, a slight improvement from 2016, when the rate was 11.1 to 1. Still, Black Iowans continue to make up 25 percent of the state’s prison population, despite being just 4 percent of the total population.
