About this data
- Smokers are people who say they smoke cigarettes, even occasionally. Estimates up to 1998 come from a survey every two years and aren't weighted to match the population; from 2000, they are annual and weighted. The survey moved from face-to-face interviews to online and telephone interviews in 2018 to 2020.
- This survey gives the longest-running series. ONS's official estimate for the UK, from the larger Annual Population Survey, is slightly higher (9.8% of adults aged 18 and over in 2025).
