I was shocked to read in this report that both downtown Ann Arbor and downtown Lansing have more workers downtown than Detroit does! Some other midwestern cities with much smaller metro populations have significantly more workers downtown! Indianapolis, Milwaukee, Cleveland to name a few. Pretty sad! Maybe some ways of measuring downtown employment use midtowns worker population of nearly 73,000 to inflate downtown's low numbers. It's so interesting to see what regions have very strong and centralized downtowns and which ones have multiple strong nodes.

The Detroit numbers are on page 35 of the report.
