As the American population continues to age, there is a growing concern in some quarters that the government and the private sector might be ill-prepared with the increased demands of an older population. The Brookings Institution published a rather insightful 28-page paper on the growth of older America, authored by noted demographer William H. Frey. Drawing on analyses performed with data from past U.S. Censuses, Frey comments on a number of trends, including the migration of older Americans into economically dynamic Sun Belt areas such as Austin, Atlanta, and Dallas. The report makes excellent use of maps, charts, and graphs that track the projected growth of senior populations by state and the counties with the fastest-growing senior population. For urbanologists and planners, this report will be quite helpful.
