Seven of our 12 county-types saw their median family incomes fall. “Immigration Nation” counties fared the worst, as Latino immigrants, many with little education, moved in. The “Service Worker Centers” also saw steep declines, as manufacturing dried up. Leading in growth were the well-educated “Monied Burbs,” where white-collar positions bloomed in office parks. Income in the “Industrial Metropolises” also rose, driven by gentrification and new wealth in inner-ring suburbs.
