The Actuarial Research Corporation under contract with the Department of Health and Human Services conducted most of the analysis. The basis for the estimates is the Medicare Current Beneficiary Survey (MCBS) for 1995. These data were aged to CY 2000, converted to a point-in-time estimate, and adjusted for the increase in managed care enrollment. This enrollment increase was estimated by moving beneficiaries from retiree health coverage, Medigap and the uninsured to managed care in proportion to their enrollment in those plans.
