Increases in the aging population and use of computer-related technology have spawned research regarding older adults' use of the Internet. This study examined characteristics differentiating rural Midwestern senior citizens (N = 298) who use e-mail from those who do not. Compared to those who did not use e-mail, e-mail-using seniors were younger and wealthier, less likely to report health-related limitations, and more likely to report being able to do things independently. Given the potential benefits associated with use of the Internet, results of studies such as this could help in identifying factors associated with successful aging. Questionnaire items are appended.
