Dataset / methodology guide · UCLA Center for Health Policy Research
Read with context.
UCLA distinguishes the main AskCHIS survey-query tool from Neighborhood Edition small-area estimates. Select an appropriate survey period and population, and retain precision flags with exported results. Pooling years can change the period represented by a claim.
Survey estimates have uncertainty. Neighborhood Edition uses a different estimation approach; its small-area values are not interchangeable with direct survey tabulations. No medical diagnosis or new estimate is supplied here.
