Method & caveats. Annual SHED, a nationally representative online survey of US adults. Combines the living comfortably and doing okay response categories. Named exception to the >=15-year minimum: SHED began in 2013, so this edition has 13 annual points through 2025. The 2020 survey was fielded in November, later than the usual timing, which may affect year-over-year comparability; no direction of bias is assumed. Breaks: 2020 survey fielded in November instead of October.
