Changes in alcohol consumption since 1990 (by country, age and gender)

The non-drinker equivalence (NDE) is one measure of the relationship between alcohol consumption and health. It measures the level of alcohol consumption at which the risk of health loss for a drinker is equivalent to that of a non-drinker. For our purposes here, it can be used as a measure of change in alcohol consumption, if we measure NDE at different points in time.

One publication that does this is:

Population-level risks of alcohol consumption by amount, geography, age, sex, and year: a systematic analysis for the Global Burden of Disease Study 2020.

It has a giant table that contains the number and proportion of the population consuming in excess of the non-drinker equivalence in 2020, and the percentage change in NDE since 1990. I will look at this percentage here, because it allows us to sub-divide the population and look at the data in various ways.

Data are shown in that table for the whole world plus separately for each of 20 sub-regions, and separately for males and females. There are also three age groups considered: 

• 15–39 years    roughly: Millennials + Generation Z (15–44 years)
• 40–64 years    roughly: Generation X (45–60 years)
• ≥65 years       roughly: Baby Boomers (≥61 years)

Here is my summary of the data from that table. The numbers refer to the percent change in NDE in the 30 years between 1990 and 2020, which for our purposes simply measures the change in alcohol consumption (as a proportion of the population consuming a specified amount of alcohol).

Looking at the Global data (row 1), you will note that there was a much bigger reduction among the two groups of younger people (for both sexes) than among the oldest group, although the latter group also reduced their consumption. So, alcohol consumption has generally been decreasing over the past three decades, and more so among younger people.

If we look at those separate regions that have had a consistent large decrease across all age/gender groups, it includes: 

High–income Asia Pacific; Southern Latin America; Oceania; and Central sub-Saharan Africa.

If, on the other hand, we look at those regions that have had a consistent increase across all groups, there has been:

Central Europe; Andean Latin America; Tropical Latin America; South Asia; and Eastern sub-Saharan Africa.

The biggest increases have been among:

• Tropical Latin America; and Andean Latin America
• Central Europe
• South Asia; and Southeast Asia among males
• Australasia among older people.

Among the youngest people, we have had the biggest reduction among:

High–income North America; and then Eastern Europe; Australasia; and Western Europe.

Among the oldest people, we have had few reductions, and they were mostly small. The biggest increases were among:

Central Europe; Australasia; High–income North America; and Southeast Asia males.

Clearly the world of alcohol consumption has been changing over the past three decades. However, there does not seem to be much consistency among those regions showing similar patterns of change among themselves; so I do not think that I can say much more here. However, it is worth noting that, in a similar manner, per capita consumption in litres of pure alcohol across the 10 markets surveyed by IWSR has fallen by 20% since 2000 (How is the moderation trend evolving?).

Moreover, we do have to accept the fact that Baby Boomers are getting too old to drink alcohol as much as before, or they are (sadly) dying. The subsequent generations do not look like they are taking up the slack (yet?). So, given the patterns noted above for the youngest generation, we might seriously wonder:

Why the wine trade should talk up its entry-level offering.

With older, high-spending, wine-loving consumers leaving the market, here Patrick Schmitt wonders whether the drinks trade should put more emphasis on inexpensive wines for a less affluent, younger generation. Indeed so.
