Des Moines Register: Des Moines’ immigrant population was among the fastest-growing in the country over the past decade. The number of foreign-born residents living in the metro area increased from about 40,000 in 2010 to about 60,000 in 2019, one of the highest rates of growth in the United States during that period, according to a report released today by think tank Heartland Forward. That’s more than a fifth of the metro area’s total estimated population growth from 2010 to 2019. The study ranked Greater Des Moines’ immigrant population growth as the second-fastest of any metro area in the country during the last decade, behind Charleston, S.C., — though the margin of error for the data, based on U.S. Census American Community Survey estimates, is too wide to make the ranking precise.
