In analyses stratified by Census region, urbanicity, age, annual household income, and health insurance, similar racial and ethnic patterns emerged in most sociodemographic strata (Supplementary Figure, https://stacks.cdc.gov/view/cdc/118051). Asian adults had the highest coverage in all months since April 2021, and in November 2021, had the highest coverage across almost all sociodemographic categories, ranging from 87.2% among the uninsured to 98.1% in persons aged 50–64 years (Supplementary Table, https://stacks.cdc.gov/view/cdc/118052). By November 2021, coverage among Hispanic adults reached or exceeded that of White adults in all sociodemographic categories except those in the Midwest Census region (difference = −3.7). Differences in coverage among Black and NH/OPI adults were no longer present in November 2021, except in the Midwest (−5.4), urban areas (−6.6), and among those aged 18–29 years (−4.2) for Black adults, and in the Midwest (−24.3), South (−19.0), and among persons aged 18–29 years (−14.1) for NH/OPI adults.
Within racial and ethnic groups, coverage varied by subgroup. For example, among Asian adults, coverage ranged from 97.8% among persons identifying as Asian Indian, to 86.5% among other Asian persons (Table 2). Among Hispanic adults, coverage ranged from 90.6% among persons identifying as South American, to 79.3% among those identifying as Mexican. Coverage among Black adults was similar across subgroups (range = 73.6%–79.8%), with the exception of adults identifying as Somali (coverage = 52.6%).
