A study released Wednesday found that immigrants, who accounted for 9.4% of Wayne County's population in 2017, contributed more than $10.5 billion to the county's gross domestic product.

The study was a collaboration between New American Economy, a bipartisan research and advocacy organization, the Office of the Wayne County Executive and Wayne United.

Wayne County's population in 2017 consisted of 164,442 immigrants with the top five countries of origin being Yemen (14.5%), Mexico (13%), India (10.9%), Lebanon (9.1%) and Bangladesh (5.7%). Immigrant households earned $4.3 billion that year, and from that $736.3 million went to federal taxes and $345.9 million to local and state taxes, according to the study.

"When you look at the numbers, the economic case for inclusion and welcoming immigrants is irrefutable -- Wayne County continues to benefit from its diversity dividend," Wayne County Executive Warren Evans said. "As we try to build a more prosperous county and future, we need to help raise awareness about the key roles immigrants play across economic sectors and in our communities."

Immigrants accounted for 11.5% of the working-age population in the county, the study found. This population makes up 16.3% of Wayne County business owners.
