Alcohol consumption in the Netherlands increased at a very fast rate f
rom 1960 to 1975, especially among young men. The question is raised w
hether members of the cohort that started drinking during the 1960s sh
ow a lasting deviation from cohorts born earlier with respect to drink
ing behavior. Cohort analysis is used to assess the effects of aging,
period and cohort membership on changes in abstinence, mean consumptio
n and heavy drinking in the Netherlands in the last three decades. Soc
ial interaction theory (Skog, 1980) is used as an interpretative frame
work. Conclusions are that abstinence is related to aging, while mean
consumption and heavy drinking are associated with period effects. Pop
ulations of men and women appear to change drinking behavior collectiv
ely. Results on women are more regular than those on men.
