By Fannie's definition there is.
Exactly. I live in a community called "Fairmount" or the township name "Felker" - but this includes 2 newish greenfield subdivisions, a large lot executive homes subdivision, some houses 80 years old, some 30, some new, some 1,000 SF and a few that are above 3,000 SF. Like a lot of rural areas, the "styles" are all over the map. A rural fire dept and a city fire department splits the township into 2 fire districts, the mail routes are part one town and another, the school district likewise has some parts in one city and then another, and a small, incorporated town lies next to it. There is no uniformity except being uniformly ununiform.
