The lottery is a form of gambling in which numbers are drawn for a prize. Prizes can range from cash to housing units to kindergarten placements, but most states offer a money prize. The lottery is popular, even though its odds of winning are relatively low. Some states even endorse a message that plays on people’s idea of “civic duty.” It’s as if lottery players are supposed to feel like they are doing their part to support the state when they buy a ticket.

Lotteries have a long history. The casting of lots to determine fates and awards dates back to biblical times. Its use as a mechanism to raise funds for public purposes is more recent, however. The first recorded public lottery was organized by Augustus Caesar for municipal repairs in Rome, and the prizes were articles of unequal value.

The modern lottery is a complex affair. The state establishes a monopoly by law; sets up a commission or public corporation to run it; initially offers a limited number of games; and then, largely due to pressure for revenue, progressively expands the game offerings. The resulting mix of games has a wide array of stakeholder interests and, consequently, the potential for corruption.

The average player spends about $1 a week on lottery tickets. But the real moneymaker is the group of people who play regularly: disproportionately lower-income, less educated, and nonwhite, with one in eight buying a ticket each week. That group contributes billions to state receipts, which are money that could otherwise be saved for retirement or college tuition.
