Beginning with the redesigned 2014 SIPP Panel, individuals who are less than one year old at the time of interview do not receive proxy health insurance interview questions.  However, some health insurance information is collected indirectly on these infants.  Each individual age one and older (or a proxy respondent) is asked about their health insurance coverage.   For each type of coverage, if the person is covered, the interviewer asks who else in the household had that coverage the same months as the individual.  Thus, if the infant has the same coverage as another household member for the same months as that person, the infant will have his or her health insurance reported.  However, coverage will not be captured if the infant has a different type of coverage or is covered different months from the household member who reported the coverage.

Infants are particularly unlikely to be covered the same months as other household members, since they are born during the reference year.  We impute the missing health insurance information for infants using the same model based imputation methods as with other missing health insurance data.  However, users should be aware that imputation rates will be unusually high for infants.
