The U.S. Census Bureau defines a foreign-born person as “anyone who was not a U.S. citizen at birth. This includes respondents who indicated they were a U.S. citizen by naturalization or not a U.S. citizen. Persons born abroad of American parents or born in Puerto Rico or other U.S. Island Areas are not considered foreign born.”

In 2012, 12.9 percent of the U.S. population was foreign-born and 6 percent of Michigan’s population was foreign-born, according to American Community Survey. While no county in Southeast Michigan had a higher percentage of foreign-born residents than the entire United States overall, four of the seven counties in the region did have a higher foreign-born population percentage than Michigan.

We saw in a previous post that Oakland County had the highest percentage of refugee residents in the region in 2012. This post shows that Washtenaw County had the highest percentage of foreign-born residents in that same year.

As noted, Washtenaw County had the highest percentage of foreign-born residents in 2012. During that time, 11.4 percent of Washtenaw County’s population was made up of foreign-born residents. Oakland and Macomb counties, which had the largest refugee populations, were the only other counties in the region where more than 10 percent of the population was made of foreign-born residents. In Oakland County, 11.2 percent of the population was foreign-born and in Macomb County 10 percent of the population was foreign-born.

Monroe County had the lowest percentage of foreign-born residents at 2 percent.

We see above that much of the foreign-born population in Washtenaw County resided in and around Ann Arbor.  Within Ann Arbor and portions of Scio, Pittsfield and Ypsilaniti we see that the foreign-born population made up 20 percent or more of the population. Throughout the rest of the county though, particularly the west side, the foreign-born population made up less than 5 percent of the population.

Wayne County, which had a foreign-born population of 7.7 percent, had both the municipality with the highest percentage of foreign-born residents and the lowest. The foreign-born population in Hamtramck made up 43.1 percent of the city’s population. Highland Park’s population was only made up of .4 percent of foreign-born residents.

Other municipalities throughout the tri-county region where more than 4 percent of the population was foreign-born were: Detroit (Wayne), Dearborn (Wayne), West Bloomfield (Oakland), Troy (Oakland) and Sterling Heights (Macomb).

In Detroit, where 5.1 percent of the population was foreign-born, the majority of these residents resided in and around Southwest Detroit. In Southwest Detroit, that neighborhood’s population was 47 percent foreign-born. Springwells, West Riverfront, Vernor, Chadsey, Hubbard, and Boynton were other Detroit neighborhoods where 20 percent of more of the population was foreign-born. As we learned in a previous post, much of the foreign-born people living in this area of Detroit are of Hispanic descent.
