What was the percentage of workers with health insurance coverage who were required to help contribute toward the cost of single coverage in 1999? What is the figure for the most recent year shown? What is a possible explanation for the trends in health insurance coverage and the fraction of workers required to help pay for their own coverage? Go to the Bureau of Labor Statistics National Compensation Survey—Benefits Web site ( http://www.bls.gov/ncs/ebs/home.htm ) and select “Top Picks” under EBS Databases. Then click on “Percent of All Workers Participating in Medical Care Benefits,” “Percent of All Workers with Medical Care Required to Contribute Toward Cost of Single Coverage,” and “All Years.” This will retrieve the percentage of workers with health insurance coverage at private establishments as well as the percentage of covered workers required to help pay for their own coverage.
