Ever wondered who drinks the most?

According to a new study by the Organization of Economic Cooperation (OECD), a international group which measures worldwide trends, highly-educated, wealthy men are more likely to knock them back more than any other group studied.

But wealthy women and poor men are most likely to abuse alcohol or take part in “hazardous drinking,” says the study.

The report detailed alcohol’s harmful effects, including health problems, work place accidents and decreased economic output. For example, in some countries the determents of drinking can cost up to 1 percent of economic growth. In the U.S. where the economy grew by $650 billion last year, that amounts to about $6.5 billion in health care expenses and costs related to crime in 2014.
