Estimated Effects of Different Alcohol Taxation and Price Policies on Health Inequalities: A Mathematical Modelling Study
Fig 1
Distribution of alcohol purchasing by income.
This figure shows the average number of units purchased per moderate drinker per year for alcohol across price bands, stratified by income. Moderate drinkers (a) purchase little alcohol overall and show a preference for middle and higher price bands, even when having lower incomes. Increasing risk drinkers (b) purchase alcohol across all price bands, but there is a clear gradient whereby poorer drinkers purchase more of the cheapest alcohol. Heavy drinkers (c)—across income quintiles, but especially poorer heavy drinkers—show a very clear preference for cheaper alcohol. Price bands are deciles of the price distribution of all alcohol sold in England. Income groups are defined by equivalised income quintiles.
