The National Immunization Survey    (NIS), the Survey of Families with Young Children (SFYC), and the Survey of Children with    Special Health Care Needs (CSHCN) collect information on the immunization coverage and    health care of children across the United States. These surveys are a collaborative effort    between the National Center for Health Statistics and the National Immunization Program.    Both agencies are part of the Centers for Disease Control and Prevention in the U.S.    Department of Health and Human Services. These surveys are sponsored, in part, by the **American Academy of Pediatrics**, the **Maternal and Child Health Bureau**, and    the **Health Resources and Services Administration**.

All three surveys are conducted by    telephone. Telephone numbers are randomly generated and selected by computer from all over    the country. A letter from the Director of the National Center for Health Statistics is    then mailed in advance to many households. All three surveys are not conducted in each    household selected. Rather, the surveys are assigned to households based on a random    selection procedure and based on the ages of children living in the household. Nobody is    asked to complete more than two surveys, and most families with children are asked to    complete only one.
**National Immunization SurveyData collection began in 1994.The study has two parts:**1.** A household telephone survey. This survey asks questions about    childhood immunization for children 19-35 months of age and requests parental permission    for contacting children's vaccination providers. Data are used primarily to monitor    immunization coverage in the preschool population in 78 nonoverlapping geographic areas.**2.** A survey of vaccination providers. This survey of doctors and other    providers is conducted for study participants who have provided consent for this phase of    the study.Overview of the study in **English**    or **Spanish**Answers to frequently asked questions about the **household telephone survey** or the **survey of vaccination providers**.For additional information, please visit the    National Immunization Survey Web site at **Abt    Associates Inc.**, the study's contractor.Data are released in the **Morbidity and Mortality Weekly Report**,    published by the Centers for Disease Control and Prevention, as well as other publications    and journals.
