Gambling problems are a serious issue for people living in poverty. The authors reviewed 27 research studies to determine how common gambling problems are for people in poverty. These studies suggest that people are more likely to develop gambling problems if they live in disadvantaged communities, have low incomes, are jobless, experience homelessness or use shelters, are in treatment for drug or alcohol addiction, and are suffering from serious health problems. Policy makers can work with service providers to create integrated programs that support people living in poverty who experience gambling and other health concerns.
