General description

Information on general health and illness of adults in Wales by health board.

Data collection and calculation

Information is collected via the National Survey for Wales. Based on a sample survey. Sample sizes for some groups are relatively small, and the results should be treated with caution. 95% confidence intervals and sample sizes are also shown to give an indication of the precision of results. The National Survey 2020-21 was adapted due to the coronavirus pandemic, and results from 2020-21 onwards should not be compared with results from previous editions of the National Survey for Wales.
