Information about health insurance has been collected periodically as a part of the Health Interview Survey. The most recent report containing such data is “Hospital and Surgical Insurance Coverage, United States, 1968,” Vital and Health Statistics (DHEW Pub. No. (HSM) 72-1033, Series 10, No. 66). Prior to 1970, the proportion of the total civilian, noninstitutional population with health insurance coverage had gradually increased. The majority of this increase occurred among persons 65 years of age and over. With the advent of Medicare, almost all persons in this age group had health insurance coverage.
