Lottery is a type of gambling in which numbers are drawn at random to determine a winner. A popular example of a lottery is the Powerball, which offers a jackpot prize of millions of dollars. In the United States, state lotteries are common and operate independently of the federal government. A number of private companies also operate lotteries.

In the seventeenth century, public lotteries were common throughout Europe and the Americas, often used to raise funds for local needs or as a painless form of taxation. The American Revolution saw Benjamin Franklin sponsor a lottery to buy cannons for Philadelphia. Thomas Jefferson held a lottery in 1826 to alleviate crushing debts.

The modern state lottery was first introduced in New Hampshire in 1964 and has since spread to 42 states. Lottery advocates argue that the games are a good source of revenue for states and that they benefit society through education, infrastructure, social services, and health care.

A large number of people play the lottery, but the vast majority are not compulsive gamblers. The average lottery player does not spend more than a few dollars per week, and most do not invest their entire income. Rather, they purchase tickets as an occasional diversion and a small chance of winning a substantial sum of money.

Surveys have shown that, as a whole, lottery participants are relatively well educated, and most live in middle-income neighborhoods. However, some socio-economic groups play the lottery at higher rates than others: men play more frequently than women; blacks and Hispanics play at lower rates than whites; and the young and old play less frequently than those in the middle age range.
