Close enough. As of the 2010 census, Dearborn is 41.7% Arab, which is a big enough group that, if they stick together, creates effective control of city government. Within a few years, expect them to drive out anybody who doesn't act in accordance with Sharia.
There's a section of East Dearborn that's largely Muslim. (Fordson HS is part of that) Dearborn itself is still majority white ethnic Catholic (Italian, Irish, Polish) and its city council is still majority white ethnic as well. It's state rep is Armenian and before that Italian.
As far as Sharia Law goes, the sky isn't falling, and it's not in effect. It's a city of under 100,000 people as well.
