Leverage Data to Drive Change!

Estimates from the 2021 National Survey of Children's Health are now available on 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 2021 National Survey of Children's Health (NSCH) Child and Family Health Measures. These estimates are available through the interactive data query on childhealthdata.org! The combined 2020 and 2021 NSCH data is also accessible on the DRC’s Interactive Data Query.   


The 2021 NSCH is the 6th single-year dataset since the redesign of the NSCH in 2016. Containing data from 50,892 children ages 0-17 years, the 2021 NSCH includes new data assessing the impact of the coronavirus pandemic on health care utilization and child care.


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.


2021 NSCH downloadable datasets and codebooks with the constructed variables displayed on the DRC’s Interactive Data Query will be available in May 2023.
