Variable Definition
An interactive month-by-month event history calendar (EHC) covering the 2-year observation period before the interview was completed for each adult respondent. Interviewers asked a series of questions to capture the start and end dates of periods within various domains such as place of residence, employment, and public assistance receipt (Temporary Assistance for Needy Families, General Relief, Supplemental Security Income, or Food Stamps). After the questions were completed for all domains, respondents were asked about health insurance coverage. The beginning and end dates of each period of insurance or uninsurance were recorded, until all months in the 2-year observation period were accounted for. For each period, respondents reported whether they were insured and the type of health insurance or reason for uninsurance.
