The prevalence of past or present infection with hepatitis B virus among adults aged ≥18 years declined from 5.7% in 1999–2002 to 4.3% in 2015–2018. A decline among non-Hispanic White (3.5% to 2.1%), non-Hispanic Black (15.6% to 10.8%), and Mexican American (3.5% to 1.8%) adults also occurred over the same period. Prevalence was higher among non-Hispanic Black adults than among both non-Hispanic White and Mexican American adults for all periods.

Percentages are age-adjusted by the direct method to the 2000 projected U.S. population using age groups 18–29, 30–39, 40–49, 50–59, and ≥60 years.

Estimates of past or present infection with hepatitis B virus are based on tests for antibody to hepatitis B core antigen in serum collected during the examination component of the National Health and Nutrition Examination Survey.
