If someone is seeing a 18Cleveland/08Detroit resemblance in "profile", the data or data sources for these "facts" best be quadruple checked.
Detroit's; 2X the size @ 700k pop, +80% African American, 10% white non-hispanic, single industry automotive focused, for a start.
Cleveland's; 300k population, 50% African American, 40% white non-hispanic, and carries health care, insurance, manufacturing (Probably 70% non-auto), and financial sector jobs. Their largest employer Cleveland Clinic has 32k employees in the city which is more than the top 5 Detroit employers combined.
Unlike Detroit, employees drive into the city enmasse for work instead of to the suburbs to massive sprawling factories. It's clear even from a 1000ft view that Cleveland is well diversified. Preventing a potential meltdown like Detroit saw.
That being said you can easily choose a poor area without a knowledgeable team. These small city neighborhoods vary in quality and desirability block to block, not by zipcode.
