Although 26 percent of the American population have health coverage through public programs, the majority of Americans, approximately 61 percent in 1994, are covered by health insurance arranged through their place of employment.2 The private sector is especially important when it comes to the coverage of children, because in 1995 approximately 59 percent of children were covered by their parents' employer-based plans. Eighty-three percent of the 9.8 million children who are not presently covered are dependents of working Americans.3 This appendix will look at the history and present characteristics of private sector health insurance and the pros and cons of several policy proposals designed to increase health insurance coverage for children.
A Brief History Of Employer-Based Health Insurance
The history of health insurance in the United States has always been tied to the development of modern medicine. There was little reason to buy health insurance until medicine created the ability to affect medical outcomes. The cost of these new forms of medical care created a desire to spread the risk of a relatively large medical expenditure among a large number of individuals, any one of whom would face a low probability of an expensive medical condition.4 Although the development of modern scientific medicine can be traced to the 19th century, several developments during and after World War II were most important in shaping the unique form of health insurance in the United States.5
