The top 10 percent of U.S. counties in terms of percent 60+ in-migrants (about 300 counties) received over 1 million new 60+ residents between 1995 and 2000 –representing about 20 percent of their total population age 60+. Many of these retirement destination counties are found in the South and West, and often they are smaller counties where more moderate absolute migration volumes represented relatively large shares of total population. Top destination counties tend to have higher average temperatures, lower crime, lower property and state income tax rates, and higher percentages of recreation/entertainment employment, and are often non-metro counties with high percentages of federal lands – areas that tend to be rich in natural amenities, mostly in the western half of the country.
