Lottery (from Latin loterium, from the drawing of lots) is a system for awarding prizes to people who buy tickets. In modern times it has become popular as a method of raising money for public projects and other charitable causes. It has also been used for sports competitions, such as horse racing and football matches. A lottery is a form of gambling, but it differs from the usual forms of gambling in that the winnings are not immediately received but only announced at some later date. In addition, there are often requirements that the winners must meet to be eligible for a prize.

The concept of distributing goods or services by drawing lots has long been a part of human culture. In fact, the casting of lots to determine rights and obligations was recorded in the Old Testament and in other ancient documents. More recently, it has been employed by both governments and private organizations to raise funds for towns, wars, colleges, and public works projects.

In the United States, state-sponsored lotteries emerged in the nineteenth century and have since grown to be a major source of government revenue. Unlike general tax revenues, which must be directed to many different programs and used according to political considerations, lottery profits are earmarked for specific purposes. This enables the legislature to reduce the amount of its regular appropriations for a program and frees up additional funds for other purposes. Critics charge, however, that this “earmarking” has not actually increased funding for the targeted program; instead, it simply allows the legislator to reduce its appropriations for the program by an equivalent amount and then use the saved monies for other purposes.

A number of issues have arisen concerning the operation and administration of lotteries. A primary problem is the fact that a substantial proportion of the total income from ticket sales goes toward organizing and promoting the lottery and as administrative expenses. This leaves a relatively small percentage for the prizes, and there is considerable controversy over whether this portion of the total should be set aside as larger prizes or as many smaller ones.

Another issue concerns the participation of different groups in a lottery. For example, men tend to play more than women; blacks and Hispanics participate at higher levels than whites; and the elderly and the young play less than middle-age adults.

These differences may reflect cultural factors, social attitudes about gambling, or even the degree to which a lottery is perceived as a way of escaping from financial hardship. In any case, it is clear that the objective fiscal health of a state does not seem to affect its willingness to establish and maintain a lottery. Rather, lottery officials develop extensive, specific constituencies: convenience store owners and suppliers; teachers (in states where the proceeds are earmarked for education); and state legislators (who quickly become accustomed to a steady stream of extra revenue). This is a classic case of public policy being made piecemeal and incrementally, with little or no overall overview.
