Recent census data indicates that immigration is the primary driver of population growth in major metropolitan areas across the United States. As urban counties experience an upsurge in numbers, the data shows that immigration has now accounted for the entirety of U.S. population growth for the first time. In areas like Chicago and Metro Detroit, immigrants have not only influenced demographic changes but have also mitigated population declines traditionally associated with resident outmigration. Further statistics reveal that most Michigan counties have also seen population increases, buoyed by the influx of newcomers. Overall, the findings highlight the significant role immigrants play in revitalizing urban regions and contributing to economic growth.
