Along North Park, South Park, and Shaker Boulevards in Shaker Heights, you'll find houses whose prices easily top the $3MM mark. These are monuments to old money—gated, with private swimming pools, tennis courts, and some of them sit on lots of an acre or more. These neighborhoods make Beverly Hills, CA look like a trailer park

Elsewhere in Shaker, the homes are more modest, but still historic and loaded with charm. Much of Shaker Heights was built in the 1900-1940 era.
As far as diversity goes, Shaker has a much broader mix of Blacks, Jews, and white Anglo's than would normally be expected of a suburb with its patrician pedigree.
Is Shaker the highest-
income place in NE Ohio? Not by a long shot. Its population is good-sized (28,000?) and a lot of residents there
don't live in the baronial mansions of the Boulevards listed above. Many Shaker folks, in fact, could be considered middle-class people who pay upper-class taxes!
I would say Shaker is about as safe as any place you'll find in the overall Heights area, unless you want to go
way out east in the county—where it's very safe, quiet, and less diverse.
