For the people who had lower incomes, there was a lot more variation in how much people drank. Some drank heavily, while others not at all. People with higher incomes were more likely to drink, but also more likely to moderate their drinking.
Genetics played a larger role in the drinking habits of lower-income people, with environmental influences having the bigger influence among the higher-income people.
The study used 672 pairs of adult twins as the basis of their study, since they are the best example of two people who share both genetic makeup and childhood environment. They were all interviewed twice, 10 years apart. Some of the twins were identical, with the same genes, while others were fraternal, making them as genetically linked as any other siblings. Each pair also had the same environment growing up.
NPR states that the fact that genetics are more of a factor in the drinking habits of lower income people supports the "widely held belief that the stresses of being poor could trigger genetic vulnerabilities".
