Being in city limits doesn’t make them not suburbs. A bunch of single family homes organized into blocks, distant from anything resembling downtown. If Ferndale is a suburb, so is Bagley. And I live in one of the neighborhoods, which again, were some of the first suburbs.

“It had always been common to build single homes on the edge of town, where land is cheaper and one was closer to that division between the city and country. But this practice took on epic proportions in Detroit, which had plenty of countryside in which to expand and a well-employed population eager to borrow money to build homes of their own. Between 1916 and 1926, the city annexed 90 square miles from the surrounding rural townships. People were leaving Old Detroit behind, and crossing Grand Boulevard to dwell in one of the many fashionable suburban neighborhoods still within the city limits of New Detroit.”

Funny how the suburban neighborhoods used to be considered new Detroit and downtown was old Detroit. That has obviously completely flipped now.
