As state officials and nonprofit groups target hard-to-count groups like immigrants, people of color and those in poverty, many Arab Americans say the undercount is even more pronounced for them. That means one of the largest and most concentrated Arab populations outside the Middle East — those in the Detroit area — could be missing out on federal funding for education, health care, crime prevention and other programs that the census determines how to divvy up. That also includes money to help states address the fallout from the coronavirus.
