This data provides information about general health and illness of adults living in Wales for May 2020 to March 2021.

The National Survey 2020-21 was adapted due to the coronavirus pandemic (with telephone interviews replacing face-to-face interviews and some changes to content). The results for general health and illness should not be compared with results from previous editions of the National Survey for Wales.

Main points

  • 76% of adults reported good or very good general health (May 2020 to March 2021)
  • 46% of adults reported a longstanding illness (October 2020 to March 2021)
  • 31% of adults reported a limiting longstanding illness (October 2020 to March 2021)
