As the elderly population of the United States grows in absolute number and as a proportion of total population, accurate projections of that population become increasingly important for sound policy decisions. Cohort component techniques are typically used for state and local projections of the elderly population, but are often outdated or even nonexistent for many local areas. This paper suggests an altemative approach, based on Medicare data and simple projection techniques.

The temporary migration of elderly adults has a major impact on the resident populations of both sending and receiving communities. This article presents a methodology for estimating temporary migration and provides insights into migratory patterns that cannot be achieved by focusing solely on changes in place of usual residence.

The elderly population of the United States is large and growing rapidly. In 2000, there were 35 million persons aged 65 and older, making up 12% of the total population. This population is projected to exceed 86 million by 2050, making up 21% of the total (U.S. Census Bureau, 2004). The oldest segment of the elderly population is growing particularly rapidly, with the population aged 85 and over projected to grow more than five-fold between 2000 and 2050, from 4 million to 21 million.
