Only 45% of those who go out to drink and eat consume alcohol, according at a study held by responsible drinking association Entreprise et Prévention.
A similar study in 2008 showed 26.7% of those asked drank alcohol when they went to a bar or restaurant.
Older generations are more likely to drink, the current survey also found, with 30% of the 55 plus age group consuming alcohol, compared to 15% for the 18-24-year-olds.
The survey also revealed that, as the age-old stereotype suggests, French consumption of alcohol is linked to meal times – of those asked, 40% drank with lunch, and 40% with dinner. Only 18% drank outside meal times.
