Cleveland could have a bit of the same scenario given all the smaller population centers that exist in NE Ohio. But Cleveland's home county (Cuyahoga) directly abuts Akron's home county (Summit), so less sprawl was needed to connect the two. Really, Cleveland and Akron should be a single MSA, but I guess that's a different discussion!

I calculated using the current CSA definition so that it was consistent.
The ratio of core MSA to CSA has has been between 80-86% since 1920. It has started to slide back towards 80% in recent decades, which it hasn't dipped below since the early 1900s, but has yet to fall below that threshold. Metro Detroit's counties have pretty large land areas, and Wayne is still the only one that has been almost completely built out. So despite how far from the city the region has sprawled, it is still mostly contained in the original footprint of the MSA.
