These estimates reflect coverage for any portion of the year by private or public health insurance, except for estimates for children and youth with special health care needs, which reflect coverage at the time of the survey. Public health insurance consists primarily of Medicaid, but also includes Medicare, State Children’s Health Insurance Programs (SCHIP/CHIP), and the Medical Care Program of the Uniformed Services (CHAMPUS/Tricare).
In 2013, there was a redesign in the way questions about health insurance were asked. These changes were meant to enhance reporting for earlier time periods, along information about other people in the household and the type of coverage. More details on the changes and their effects are available at https://www.census.gov/srd/papers/pdf/RSM2014-02.pdf.

 Beginning in 2002, the Census allowed respondents to select more than one racial category. The white, black and Asian categories refer to those who selected only one race. Hispanic children may be of any race, while white children in this report do not include Hispanic youth.
