What the answer means
The percentage includes all ages within the civilian noninstitutionalized population. It does not include institutionalized residents or active-duty Armed Forces members. A coverage statistic cannot show appointment availability, treatment quality or an individual’s medical needs.
Institutionalized people and active-duty military are outside this universe. Coverage does not establish access to care or personal health.
How to check it
The chart, answer sentence, indicator and download use one approved observation, rather than separately maintained numbers. The displayed percentage is rounded; the table and export preserve the calculation’s precision. Reference period, population universe and source version are part of the figure.
Inspect the indicator definition, formula and state table . The source is the U.S. Census Bureau, ACS 2024 five-year detailed tables, B27001, released January 29, 2026. The source files were acquired September 30, 2026; this metadata-corrected snapshot was published October 1, 2026.
Before comparing places
Compare the same measure and survey product with the same definition. A difference between two estimates is a descriptive observation, not proof of a meaningful change, a policy effect or an individual outcome. Derived percentages have no calculated margin of error in this release; source component MOEs remain in the raw data.
