Attention! The Maternal and Child Health Bureau and the Census Bureau revised imputation and weighting by race and ethnicity for the 2021 and 2022 NSCH. 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.
The updated weights have been applied to the 2022 NSCH DRC constructed dataset and data query findings. The updated weights have not been amended in the datasets and data
query findings prior to 2022. Due to the imputation and weighting changes, the estimates produced
using the U.S. Census Bureau’s public use files with the new weights are not comparable to the
estimates on the DRC data query and DRC constructed datasets prior to 2022. The DRC indicators and
measures displayed on the interactive data query prior to 2022 can be recreated with updated weights
by applying the codes available in the DRC codebook(s) to updated public use files provided on the U.S.Census Bureau’s website.
