Gambling involves risking something of value (money, property or other assets) on an event that is largely based on chance in the hope of realizing a profit. It has been around in virtually every society since prerecorded history and is often incorporated into local customs and rites of passage. It has made millionaires and broken families, but it also creates excitement, fantasy and moments of grandeur. It has sparked pro- and anti-gambling movements that seem to ebb and flow.

Different ways have been used to study gambling’s impacts, including a cost-benefit analysis approach that aggregates changes in monetary values and attempts to determine whether these changes are positive for society. A broader view of gambling’s costs and benefits, incorporating both monetary and intangible elements, has also been used to assess its impact. Social impacts are defined by Williams and Walker as those costs or benefits that are not merely personal, but affect others in the community.

A societal level approach is also possible, in which the effects of gambling are measured by the amount of money it brings in and the number of jobs it generates. This measure allows researchers to compare the economic impacts of gambling to other industries, such as tourism and infrastructure, and to assess whether government policies are effective in reducing the negative impact of gambling.

Regardless of which approach is taken, it’s important to remember that gambling is not a profitable way to make money; you are almost guaranteed to lose. Always start with a fixed amount of money you are ready to lose and do not be afraid to walk away from a table if you’re losing. Also, it’s not smart to tip cocktail waitresses in cash, so always give them a $1-$5 chip instead.
