Meric) (Newser) – Wealthy Americans are on the move, largely to the low-income-tax havens of the Sunbelt. A new Forbes analysis of IRS data from 2008 shows Collier County, Fla., at the head of the pack, picking up 15,150 new residents with an average income of $76,161—compared to $26,128 for the people moving away. A nifty feature on the Forbes website illustrates the migration and breaks it down by average income, county-to-county. For instance, click on New Orleans (Orleans Parish, La.) and you see graphics showing not just migration in and out but the number of people moving and their average income: to Seattle (King County, Wash.), 56 people, $36,200; from Seattle, 41 people, $25,000.
