Objectives: To aid state and local policymakers, program planners, and community advocates, we created estimates of the percentage of the population lacking health insurance in small geographic areas of California.

Methods: Finally, calibration ensured the consistency and stability of the estimates when they were aggregated.
Results: Health insurance coverage among nonelderly persons varied widely across assembly districts, from 10% to 44%. The utility of local-level estimates was most apparent when the variations in subcounty uninsured rates in Los Angeles County (19%-44%) were examined.
Conclusions: Stable and useful estimates of health insurance rates for small areas such as legislative districts can be created through use of multiple sources of publicly available data
