Private employment-based health insurance in ten states.

This Data Watch reports key findings from the 1993 Robert Wood Johnson Foundation Employer Health Insurance Survey, through which more than 20,000 employers in ten states were interviewed. Our report contrasts the behavior of four size classes of small businesses (fewer than fifty workers) with that of all other businesses. We examine offer rates by business size; characteristics of employers and workers in business offering and not offering insurance; premiums, benefits, and medical underwriting; the extent of choice among plans; and self-insurance. We discuss the implications of our findings for health policy.
