Leaving the hip cities for the heartland

Michael Barone is a premier analyst of the American scene. He says people are leaving the coastal blue states for the heartland. Given the high cost of real estate here in blue Seattle I have given thought to cashing in and moving to a cheaper state like Idaho or Montana. Barone writes in the Wall Street Journal:

Start with the Coastal Megalopolises: New York, Los Angeles, San Francisco, San Diego, Chicago (on the coast of Lake Michigan), Miami, Washington and Boston. Here is a pattern you don't find in other big cities: Americans moving out and immigrants moving in, in very large numbers, with low overall population growth. Los Angeles, defined by the Census Bureau as Los Angeles and Orange Counties, had a domestic outflow of 6% of 2000 population in six years--balanced by an immigrant inflow of 6%. The numbers are the same for these eight metro areas as a whole. There are some variations. New York had a domestic outflow of 8% and an immigrant inflow of 6%; San Francisco a whopping domestic outflow of 10% (the bursting of the tech bubble hurt) and an immigrant inflow of 7%. Miami and Washington had domestic outflows of only 2%, overshadowed by immigrant inflows of 8% and 5%, respectively. This is something few would have predicted 20 years ago. Americans are now moving out of, not into, coastal California and South Florida, and in very large numbers they're moving out of our largest metro areas. They're fleeing hip Boston and San Francisco, and after eight decades of moving to Washington they're moving out. The domestic outflow from these metro areas is 3.9 million people, 650,000 a year. High housing costs, high taxes, a distaste in some cases for the burgeoning immigrant populations--these are driving many Americans elsewhere.
