The following graphic caught my eye:
As you can see the top 3 spots remain unchanged: New York, LA, and Chicago. Perhaps a good comparison is the decline of other big cities in the region like Detroit, Cleveland, and Milwaukee. The only other city in the upper Midwest that did not decline was Minneapolis, which also remain unchanged. No city in the region increased spots. Also note that for all the boosterism about Indianapolis, it has fallen off the index. So would you say that Chicago and Minneapolis outperformed the region by holding their respective spots, or underperformed compared to many of the sunbelt cities that climbed up the chart?
