NCHS has updated the scheme based on the 2023 Office of Management and Budget (OMB) delineation of metropolitan and micropolitan statistical areas and information about all people living in each of the counties—its population—taken from Census' 2022 postcensal estimates of July 1, 2022. NCHS used these resources to classify U.S. counties and county equivalents into six categories—four metropolitan and two nonmetropolitan. The NCHS scheme allows researchers, policy makers, and others to study American's health in relation to the urbanization level—more urban or more rural—of the place they live. They also can use NCHS data to monitor the health of people living in urban and rural areas.
