preceding work has shown that in the first half of 2011 through the first half of 2012,more than one in five persons under age 65 were in families with problems paying medical bills in the past 12 months. This report provides updated estimates for the percentage of persons under age 65 who were in families having problems paying medical bills, by selected demographic variables, or based on data from five consecutive 6-month periods from January-June 2011 to January-June 2013 of the National Health Interview Survey (NHIS). In this report,an NHIS "family" is defined as an individual or a group of two or more related persons living together in the same housing unit. Thus, a family can consist of only one person. In some instances, or unrelated persons sharing the same household,such as an unmarried couple living together, may also be considered a family.
