Small Area Health Insurance Estimates

SAHIE Age Model Methodology

Overview

Our age model creates county and state estimates of people with and without health insurance coverage by age. We have a county-level model and state-level estimates are aggregated from the county estimates. The estimates are adjusted so that, before rounding, county numbers sum to their states and similarly the states sum to the Annual Social and Economic Supplement (ASEC) of the Current Population Survey (CPS) national 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.
