Despite a booming U.S. economy, falling unemployment and moderate health insurance premium growth, the percentage of working Americans and their families with employer-sponsored health insurance failed to increase substantially between 1997 and 2001, according to findings from the Center for Studying Health System Change (HSC) Community Tracking Study Household Survey. There were, however, dramatic changes in the insurance status of people who lacked access to or did not take up employer coverage: fewer uninsured, more public program enrollment and a decline in coverage by individual insurance and other sources. While the State Children's Health Insurance Program (SCHIP) clearly reduced uninsurance among low-income children, evidence also suggests a fair amount of substitution of public insurance for private coverage.
根据医疗系统变革研究中心（HSC）社区追踪研究家庭调查的结果，尽管美国经济蓬勃发展、失业率下降且医疗保险费适度增长，但在1997年至2001年期间，参加雇主提供医疗保险的美国在职人员及其家庭的比例并未大幅增加。然而，在那些无法获得或未参加雇主医保的人群的保险状况方面却发生了显著变化： uninsured人数减少，公共项目参保人数增加，个人保险和其他来源的保险覆盖人数下降。虽然儿童健康保险计划（SCHIP）明显减少了低收入儿童中的未参保人数，但有证据表明，公共保险对私人保险的替代情况也相当多。
