Comparability
In 1997-2003, persons could report having up to four health insurance plans. Beginning in 2004, details were only collected about two health insurance plans for each person. If a person had more than one insurance plan and indicated that someone outside the household paid for any of these plans, they are categorized as responding "Yes" to HIPOUTR. If persons with multiple plans had responses including a combination of "No" and missing responses, those person's were classified as "Unknown" in response to HIPOUTR.
