This report examines how U.S. businesses will be affected by the demographic changes in an aging society. As employers, as funders of retirement income and health programs, and as community citizens facing the needs of a graying population, businesses will need to develop new strategies to address current and future change. A concurrent trend of great importance to U.S. businesses is the rise in health care costs paid for employees, dependents, and retirees. This booklet is intended to assist company benefit managers in developing and implementing health care benefit plans. It includes six sections on issues that have a profound effect on the types and costs of health benefits that companies can provide to an aging work force: company size, the changing demographics, health profiles of the older work force, company health cost management profiles, worksite wellness activities, and attitudes and perceptions of the older worker. Each of these sections contains a statement of purpose, background information, and discussions of the implications for benefit managers and related management decisions. The final section contains strategies for employee education, benefit redesign, health program development, data access, and management education. (MN)
