What is a Lottery?

A lottery is a method of making decisions by giving everyone the same opportunity to participate. It may be used to decide who gets a job, which team members will be on a sports team, how many children one person will have, or even which university a student will go to. In a lottery, participants pay a small sum of money for the opportunity to participate in the drawing. In some lotteries, the prize is a cash reward, while in others it is goods or services. In either case, the results of a lottery are determined by chance.

The practice of lottery is ancient, dating back to biblical times when Moses was instructed by the Lord to take a census of Israel and then divide its land by lot; and to Roman emperors who used it as an entertainment at Saturnalian feasts. Lotteries have also been employed by governments to raise money for projects such as the building of the Great Wall of China, and in colonial America to fund public works including roads, libraries, schools, churches, canals, bridges, and even the founding of Princeton and Columbia universities.

But the lottery is not without its detractors, with critics arguing that it encourages addictive gambling habits, is a major regressive tax on lower-income people, and leads to other abuses. Despite these concerns, few states have repealed their lotteries. The evolution of lottery policy is typical of the way that public policy is made in the United States, with a series of individual choices and incremental changes that result in few coherent state plans or programs.
