The 2000 SAHIE experimental estimates were created to demonstrate the feasibility of producing high-quality modeled estimates of health insurance coverage by age at the state and county-level. The experimental SAHIE model utilized the Current Population Survey (CPS) in addition to other data sources. The project was done in conjunction with the Centers for Disease Control and Prevention's (CDC) Division of Cancer Prevention and Control (DCPC). The CDC have a congressional mandate to provide screening services for breast and cervical cancer to low-income, uninsured, and underserved women through the National Breast and Cervical Cancer Early Detection Program (NBCCEDP). The program had an interest in utilizing the SAHIE estimates for their program administration.

The SAHIE age model produced state and county estimates of population with and without health insurance coverage by age. Modeling was done at the county level and state estimates were created as aggregates of the county ones. The estimates were adjusted so that, before rounding, county estimates sum to their respective state estimates, and for key demographics, state estimates sum to the national 2001 CPS ASEC (which contains questions about income during calendar year 2000) civilian, non-institutional estimates.

We have developed experimental county and state estimates of people with and without health insurance coverage by age in 2000 for:

• total population;
• children under age 18; and
• measures of uncertainty of the estimates.
