Children & young people
Research evidence and prevalence are different things.
SCC Vaping keeps youth-focused literature separate from official survey estimates and retains survey, geography and demographic provenance.
Official-data safeguards
OHID
Indicators include ever use and regular e-cigarette use among 15-year-olds. Geography and survey definitions remain attached.
NHS England
The structured 2023 youth dataset covers tables 4.2–4.6. Percentages and weighted/unweighted bases must not be mixed across definitions.
Interpretation
Prevalence describes reported use in a defined survey population. It does not by itself establish causes, health effects or trajectories.
