Gambling is a form of entertainment. People gamble for a variety of reasons, including to gain social rewards, intellectual challenge, and relief from stress. However, gambling can also have negative effects.

Studies on gambling have examined both positive and negative impacts. Many studies have focused on the economic impacts. Research has measured economic benefits and costs, but less has been done on social impacts.

The main issue in gambling impact analysis is how to measure the social impact. Researchers use a public health approach to assess the impacts of gambling. They also consider the severity of the impact.

Gambling impact studies can help policymakers evaluate the consequences of different gambling policies. These studies also provide an important resource for researchers to compare the impact of different gambling policies.

Gambling is a major international commercial activity. It is legal in most countries, and the amount of money legally wagered each year is estimated to be over $10 trillion.

Gambling impacts can be seen at the individual, interpersonal, and community/society level. They can affect the life course of an individual as well as a generation.

Traditionally, people gamble by betting something of value on a random event. People who are able to predict the outcome correctly win. Similarly, people who gamble incorrectly lose. Typically, people only gamble with money that they can afford to lose.

Gambling has been linked to problems such as social isolation, reduced sense of connectedness, and increased rates of problem gambling. It is also linked to increases in crime rates and tourism.
