Attention! The Maternal and Child Health Bureau and the Census Bureau revised imputation and weighting by race and ethnicity for the 2022 NSCH. The updated weights are applied to the 2022 and 2021-2022 NSCH data but have not been applied to prior estimates on the DRC data query. Revised 2021 datasets are available on the Census Bureau’s Data Release page. These revised datasets should be used when combining with the 2022 NSCH datasets. Please read the weighting revisions technical document for more information.
