Lotteries are the most prevalent form of gambling in the United States. Playing the lottery can have a negative impact on those who engage in it heavily. Financial literacy is the ability to understand and use different types of financial knowledge to make financial decisions. This study examined the relationship between financial literacy and the frequency of buying the lottery. It used restricted-version data from the United States’ 2018 state-by-state survey of the National Financial Capability study. The survey had responses from 26,566 adults. The researcher found that greater financial literacy reduced lottery consumption of those who played moderately. But the effects of financial literacy were lessened among people who played the lottery more heavily.
