^ once again, excellent work!
and no surprises with the top 5, who stand-out from the rest of the list by quite a bit:
1. Chicago.......21,235.2
2. Cicero.......16,700.1
3. Berwyn.......15,919.5
4. Oak Park.......13,318.4
5. Evanston.......11,847.3
- gap -
6. Norwood Park.......7,866.6
7. Proviso.......7,415.0
8. Leyden.......7,260.8
9. Maine.......7,009.5
10. Niles.......6,665.9
and so on
the city is the obvious density alpha, followed by the 3 west side bungalow belt burbs and evanston as the the two most "city like" areas in the burbs that managed to evade city annexation attempts.
sidenote: i didn't know the township that is comprised of enclaved burbs Norridge and Harwood Heights is called "Norwood Park". there is also an official City of Chicago Community Area due north of that area that is also named "Norwood Park". Norwood Park the Community Area is not part of Norwood Park the Township, and vice-versa. confusing.
