Also presented as an appendix to this research are methods to harmonize insurance coverage in the CPS for all years since the inception of the State Children's Health Insurance Program. Using the 1997-2007 CPS methods are introduced to correct for various methodological and conceptual changes to the measurement of health insurance coverage in the CPS, which is the source most often used for documenting trends in coverage. Included in this, is a novel approach for correcting the change in estimates due to the introduction of the health insurance verification question in 2000. This harmonized time series can be used going forward as further attempts are made to disentangle the effects of outreach and education in stimulating enrollment in public health insurance programs.
