History of the Lottery

The lottery is an arrangement in which prizes are allocated by a process that relies entirely on chance. Typical arrangements include the awarding of housing units in a subsidized apartment building or kindergarten placements in a public school, but it may also involve prizes for sports teams or cash awards. In a lottery, each betor writes his or her name and a number on a ticket that is then deposited with the organizer for shuffling and possible selection in the drawing. Computers are increasingly being used to store information about the tickets and to generate random numbers that indicate winners.

Throughout history, state governments have adopted lotteries to raise money for various purposes. Often, these are seen as necessary supplements to other tax revenue, but studies show that they do not have much effect on the overall financial health of states. Instead, it is the sense that lotteries benefit specific public goods, such as education, that drives their popularity.

The first recorded lotteries to offer tickets for sale with prize money are found in the Low Countries of the 15th century. The towns of Ghent, Bruges and others raised funds for town fortifications and to help the poor by holding public lotteries with numbered tickets for sale. Eventually, these were replaced by a system in which a bettors selected numbers and machines randomly spit them out. Many people, however, prefer to choose their own numbers, and they may use birthdays or personal information such as their home addresses or social security numbers as the basis of their choice. These numbers tend to have patterns and are less likely to win.
