A study by the Norwegian Institute for National Health has linked greater alcohol consumption to higher education and higher income. People who have more education and more money drink more than uneducated and poorer people, the research shows.

The Norwegian study, conducted between 1993 and 2000, found that there is not necessarily a connection between the people who have higher education and the people who have a high income, but both groups consume a more alcohol.

"The main function of this survey has not been to find out how much Norwegians drink, but alcohol consumption connected to people with little or high education," Bjørn Heine Strand told the press.

Overall, the study found that Norwegians increased their drinking between 1993 and 2000, but the increase is largest among the wealthy and Norwegians with higher education.
