What is a Lottery?

A lottery is an arrangement in which one or more prizes are distributed by chance. In modern usage, the word often refers to a state-sponsored game in which people buy tickets for a chance to win a cash prize. It may also refer to other arrangements in which prizes are distributed by chance, including those used for military conscription and commercial promotions in which property is given away. It can also refer to a system in which people are chosen for jury duty by a random procedure.

Lottery has been a popular source of revenue for state governments in the United States and other countries, but critics charge that it promotes harmful behavior and is highly regressive. In the past, lottery advocates argued that lotteries allowed governments to expand their services without imposing heavy taxes on working-class families. This arrangement did not work out, and in the late 1960s states began to limit their use of the lottery.

The English word lottery is believed to have been derived from Middle Dutch loterie, a compound of Old French lotere and legere (to draw lots), or to be a calque of the Latin sortilegium “action of casting lots” (as in the drawing of a sword). In the early 1600s, the term was adopted by the English courts.

Before the 1970s, most lotteries were no more than traditional raffles, with the public buying tickets for a drawing in the future. Since then, innovations in lottery games have transformed the industry. For example, scratch-off tickets offer lower prize amounts and much higher odds of winning than the traditional tickets, making them more attractive to some players. These games are designed to be played quickly, so revenues typically increase dramatically after introduction and then level off or decline. To maintain or increase revenues, lottery operators have to introduce new games regularly.
