A competition based on chance, in which tickets bearing numbers are drawn at random to determine winners. Usually used as a means of raising money for public purposes.

The word lottery is derived from the Latin loterie, meaning “action of drawing lots.” In its earliest uses, this term probably referred to casting lots for various purposes, including making decisions and divination; see also luck, chance, and fortune. Later, it came to refer to the process of awarding prizes by chance or by drawing names. Finally, in the late sixteenth century, it began to be used to describe a public gaming operation with prize money, the first such lotteries appearing in European town records of the fourteen-hundreds. In the seventeenth century, these became popular in England and France, where lottery profits were designated for a variety of municipal purposes, from building town fortifications to assisting the poor.

A state-sponsored contest in which numbers are drawn at random to determine winners. In the United States, state lotteries are regulated by law and overseen by a state agency or commission. Most state lotteries have their own retail and distribution systems, which select and train lottery retailers, promote the games, sell and redeem tickets, pay high-tier prizes, and enforce lottery laws and rules. In addition, many state lottery divisions will also conduct research and development for new game designs.

While critics of the lottery argue that it is nothing more than a tax on the stupid, those who defend it often point to its popularity as evidence that people prefer a small chance at winning a big prize over the alternative: paying a higher percentage of their income in taxes and other government costs. Moreover, they note that lottery sales fluctuate with economic fluctuations, with higher sales occurring when unemployment and poverty rates are higher and when the media promotes the games.

The size of a jackpot is another important factor in determining lottery sales. When the prize grows to an enormous amount, it generates a huge amount of free publicity for the lottery on news sites and on television, and this helps to stimulate ticket sales. It is also worth noting that, in the early modern era, many of the states that launched lotteries were those with relatively large social safety nets and thus a greater need to raise revenue.

In fact, Cohen points out, the first state lotteries were chartered in the Northeast and in states that had been pioneering tax revolts. As a result, the lottery is a very good example of the way that government policy shifts to reflect the social and economic realities of a time.
