What is a Lottery?

A lottery is a form of gambling in which tickets are sold for a chance to win a prize determined by drawing lots. The prize money is usually cash. Lotteries are commonly organized by governments and are regulated. The first recorded public lotteries in Europe appeared in the 15th century, when towns used them to raise funds for town fortifications and to help the poor.

The practice of making decisions and determining fates by casting lots is ancient, as can be seen from references in the Old Testament where Moses was instructed to take a census and divide land among the people, and in the records of Roman emperors who used the lottery to give away property and slaves during Saturnalian feasts. The lottery was introduced to America in the 17th century, and it quickly became a popular way for states to raise money for roads, canals, bridges and churches. It also helped to fund many private projects, including the foundation of Princeton and Columbia universities.

State lotteries have historically followed remarkably similar patterns: The government legislates a monopoly for itself; establishes a state agency or public corporation to run the lottery (as opposed to licensing a private firm in return for a share of the profits); and begins operations with a modest number of relatively simple games. Under pressure for additional revenue, the lottery progressively expands the number and complexity of games offered.

Despite this, there is little evidence that lotteries are effective in raising state revenue. They are often regressive, with the rich benefiting more than the poor. The only substantial revenue stream they provide is a small percentage of total state revenues, which is not nearly enough to offset a reduction in other taxes or to meaningfully boost state spending.
