Coverage estimates focus on adults ages 19-64 without dependent children, using a national household survey of the civilian, noninstitutionalized US population sample.
The survey includes a 1% US population sample, supporting precise state-level estimates while keeping the national coverage picture consistently structured for comparison.
Respondents report coverage held at survey time, and people with multiple coverage types are assigned to one insurance category for analysis purposes.
Because coverage categories are sorted and rounded, totals may not exactly add up, so small differences should be interpreted carefully in context.
For client conversations, the key takeaway is methodological: these estimates describe survey-time coverage status, not lifetime coverage history or future enrollment patterns.
