Lottery, also known as the National Lottery in some countries, is a type of gambling in which random numbers are drawn to determine the winners. The prizes are usually cash, but may be goods or services as well. It is operated by state governments, although several private companies run national games as well.
Lotteries are a popular source of revenue, raising more than $70 billion in the United States alone during fiscal year 2014. Lottery revenues are an important contributor to many states’ budgets, and their growth has been particularly rapid since the 1980s.
While the lottery’s popularity has grown, so too have concerns about its social impacts. Among these are the potential for lottery play to compel people to gamble more heavily, especially on smaller games, as they try to overcome the odds of winning a large prize. Other issues include the regressive impact of lottery games on lower-income households and the fact that they reinforce beliefs that wealth can be acquired through chance.
Aside from these issues, a growing body of research suggests that lotteries are a poor substitute for higher taxes or other means to raise government revenues. The evidence shows that lotteries generate far less in tax revenue than their advertising claims suggest, and are unable to offset the costs of running them.
While there are a number of different ways to run a lottery, most states follow similar models: They legislate a monopoly; choose a public corporation or agency to operate it; and begin with a relatively small set of games. Then, as revenues increase, the lotteries introduce new games to maintain or expand their revenues.
