Data Alert! In 2024, the Maternal and Child Health Bureau and the Census Bureau revised imputation and weighting by race and ethnicity for the NSCH. The updated weights have not been applied to the estimates for the 2016-2021 NSCH on the DRC website. The estimates from these survey years are not comparable to estimates produced using datasets with the updated weights available on the U.S. Census Bureau’s website. These estimates also should not be directly compared with estimates on the DRC’s NSCH data query page (2021-2022, 2022 and beyond) which have been updated with new weights.
The CAHMI’s DRC datasets for 2016-2021 haven’t been updated with new weights. The indicators and measures displayed on the DRC interactive data query from the 2016-2021 NSCH can be recreated with updated weights by applying the codes available in the DRC codebooks to the updated public use files provided on the U.S. Census Bureau’s website. Please read the weighting revisions technical document for more information.
