I’m from Howard County (99.06%)
All the time it’s the crime from Waterloo and Rochester, MN that’s in the news.
I lived in Waterloo for a year a long time ago (but in a “non-diverse” neighborhood near the border with Cedar Falls). According to the 2010 census, the population of Waterloo is 77% white and a bit over 15% black (and 5% Hispanic).
