What is a Lottery?

Lottery is a form of gambling in which participants select numbers to win prizes. States have used lotteries to raise money for a variety of purposes, including education, road building and other infrastructure, and social welfare services. In the early years of American history, they were hailed as a painless alternative to traditional taxation.

Today, state lotteries are ubiquitous, and the vast majority of Americans play them at least occasionally. Most states and the District of Columbia have one or more lotteries, offering a wide variety of games including instant-win scratch-off tickets, daily game options and games that require players to pick the correct numbers in a drawing. In the United States, lottery revenues have grown dramatically since their introduction and remain a major source of state revenue. However, revenues tend to level off and even decline, due to a combination of factors that include a growing sense of boredom among lotto players and the need for new games to keep revenue levels high.

A state that introduces a lottery typically legislates a monopoly for itself; establishes a government agency or public corporation to run the lottery (as opposed to licensing a private firm in exchange for a share of profits); begins operations with a modest number of relatively simple games; and, under pressure to maintain or increase revenues, progressively adds more complex and elaborate games to its offerings. Several studies show that lottery play varies by income: the poor play less than those in middle or upper income groups, and participation declines with age.
