A lottery is a game in which numbers are drawn and prizes awarded by chance. The prize money is often a large sum of money, although other prizes are also offered. In some cases, the prize amount is a percentage of the total value of the tickets sold, which can include profits for the lottery promoter and other costs. In other cases, the prize is a fixed amount, such as the value of a property or a vehicle. Despite their many critics, lotteries have a long history and can be used for both public and private purposes.
Lotteries are often run as a means of providing goods and services for which there is a great demand without the need to raise taxes. Examples include a lottery for units in a subsidized housing block or kindergarten placements at a reputable public school. The financial lottery, which dishes out big cash prizes to paying participants, is another example.
In the immediate post-World War II period, many states viewed lotteries as a way of expanding their array of social safety net programs without increasing taxes on middle-class and working-class taxpayers. But by the 1960s, states began to see the limitations of this strategy. In order to continue delivering a large assortment of public services, they needed a new revenue source, and they turned to the lottery.
