Add Health

Initiated in 1994 and supported by five program project grants from the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) with co-funding from 23 other federal agencies and foundations, Add Health is the largest, most comprehensive, nationally-representative longitudinal survey of adolescents ever undertaken. Beginning with an in-school questionnaire administered to a nationally representative sample of students in grades 7-12, the study followed up with a series of in-home interviews conducted in 1995, 1996, 2001-02, 2008, and 2016-18. Add Health participants are now full-fledged adults, aged 33-44, and will soon be moving into midlife. Over the years, Add Health has added a substantial amount of additional data for users, including contextual data on the communities and states in which participants reside, genomic data and a range of biological health markers of participants, and parental survey data.

Multiple datasets are available for study, providing opportunities to increase knowledge in the social and behavioral sciences and many theoretical traditions. Add Health has become a global data resource for over 50,000 researchers. We encourage researchers and students of public health, human development, biomedical sciences and related fields to explore the possibilities in this rich dataset.
