In the National Survey on Children's Health (NSCH), parents report on adolescent use of preventive medical visits. The NSCH data set includes representative samples from each state and is collected on an annual basis. The sample is selected from the Census Master Address File and supplemented with an administrative records-based flag that identifies households likely to include children. The child-presence flag was developed by the Census Bureau's Center for Administrative Records Research and Applications and builds on multiple sources of administrative data. The address-based sample covers the 50 U.S. states and the District of Columbia. Data are collected using a two-phase design including a household screener used to assess the presence, basic demographic characteristics, and special health care need status of children in the home and a substantive, age-specific topical questionnaire completed for one randomly selected child in the household. The respondent is a parent or guardian who knows about the child's health and health care needs. Data are collected using one of two modesweb survey or paper questionnaire. All sampled addresses received an initial invitation letter with instructions to participate by web. The letter includes the web survey URL along with a unique username and password. Households that do not complete the survey online (and addresses identified as most likely to respond by paper) receive a paper screener questionnaire (along with the web URL and login ID).
