Similar race and ethnicity classifications are needed to identify health disparities between different groups. There are 3 broad categories of race and ethnicity classifications - surveys using versions of the OMB 1977 standards, using versions of the OMB 1997 standards, and datasets with non-standard classifications. Even datasets that use an expanded version of the OMB 1997 standards (with specific ethnicities) exclude some identities. Using specific ethnicities that people identify as results in fewer blank and “Other” responses for race and ethnicity questions. A more inclusive and consistent collection of race/ethnicity data would support research to address health disparities.
