CAHMI's Data Resource Center's Interactive Data Query

The Data Resource Center for Child and Adolescent Health (DRC), a project of the Child and Adolescent Health Measurement Initiative (CAHMI), under a cooperative agreement with the Health Resources and Services Administration’s (HRSA) Maternal and Child Health Bureau (MCHB), is excited to announce the release of the combined 2020-2021 National Survey of Children's Health (NSCH) Child and Family Health Data Findings. These estimates are available through the interactive data query on childhealthdata.org! The combined 2020-2021 NSCH is the fifth multi-year dataset since the redesign of the NSCH in 2016 and includes data from 93,669 children ages 0-17 years.


For more information about the NSCH and additional resources for data users such as fast facts, guides to topics and questions, survey methodology and instruments, a crosswalk of survey items, and more, please visit the DRC NSCH Overview page. There are also numerous resources available at HRSA MCHB’s webpage on the NSCH, including an NSCH Data Brief on the impacts of the COVID-19 Pandemic. Finally, the public use files used for the DRC's constructed variables are also available through

the U.S. Census Bureau’s NSCH page.


The combined 2020-2021 NSCH downloadable datasets and codebooks will be available in early 2023. Single year 2021 NSCH estimates, downloadable datasets, and codebooks will be available on the DRC in spring 2023.
