CHIS Methodology Documentation

Below is documentation describing methodological details of each CHIS data collection and release cycle. Methodology Briefs concisely address specific methodological issues encountered by CHIS data users. Methodology Papers are products of research projects examining CHIS data quality and innovations. Methodology Reports provide the most in-depth descriptions of our sampling, data collection, data processing, response rates, weighting and variance estimation methods (five reports per data collection/release cycle).
