The number of people lacking health insurance coverage in the U.S. is
sustained by a set of dynamic processes. Comparatively few of the uninsured
remain in that state indefinitely, but uninsured persons who gain coverage
are offset by insured persons who lose their coverage. In good economic times
the balance shifts toward the gainers, and uninsured rates tend to decline.
In weak times, the balance shifts in the reverse direction, and uninsured
rates tend to rise. Migration plays a role as well. New immigrants have much
higher uninsured rates than long-term residents, but so do those who leave
the population, which dampens the effect of immigration. Achieving a significant
reduction in the number of uninsured persons will require reducing the rate
at which people lose coverage or increasing the rate at which people (re)gain
coverage or, ideally, both. From a policy perspective, this should
focus attention on the factors that contribute to people losing or gaining
coverage, yet true longitudinal analyses of these factors are rare.
The study had four main components: (1) a literature review; (2) methodological work on the 2001 panel of the Survey of Income and Program Participation (SIPP) to identify and address limitations that represent potential sources of bias in estimates of health insurance dynamics; (3) a descriptive (or tabular) analysis of SIPP panel data to document aspects of the dynamics of health insurance coverage and (4) a multivariate analysis of events associated with transitions in health insurance coverage. The literature review and the methodological findings are presented in appendices to the report and not discussed in this summary. |
