A number of governments around the world use the lottery to raise funds for a variety of purposes, including public works projects, social welfare programs, and sports events. In an anti-tax era, lottery revenues are seen as an attractive alternative to raising taxes. However, a lottery is still a form of taxation, and the debate over its desirability has changed from the general question of whether a government should hold a lottery to more specific features of its operations, including problems of compulsive gamblers and its regressive impact on lower-income communities.

The earliest evidence of a lottery comes from the Low Countries in the 15th century, when town records indicate that lotteries were used to fund town fortifications and help the poor. More recently, lotteries have become popular forms of charity, wherein the proceeds are used to benefit a particular cause or community. However, even when the prizes are charitable, there is a strong element of gambling in lottery activities: people simply like to gamble, and many people spend a significant portion of their incomes on lottery tickets.
