WHO report on Health Behaviour in School-aged Children

The World Health Organisation has published a report on
health behaviour in 11-15 year-olds in Europe and North America.
Regarding alcohol, three measures were taken; frequency of drinking,
incidence of drunkenness and (for 15 year-olds only) whether they had
been drunk before the age of 13.

For frequency of drinking, the percentage of children
drinking at least once a week was calculated. For incidence of
drunkenness, the percentage of children who had been drunk at least
twice was calculated. 

The tables below show the findings for England, Wales,
Scotland and Ireland, together with the figures for whichever countries
had the lowest and highest percentages (based on boys and girls
combined) and the average across all countries.
