What Is a Lottery?

The drawing of lots is a time-honored practice that has been used for centuries to determine ownership or other rights. During the eighteenth and nineteenth centuries, it became more widely used in state-sponsored lotteries as governments sought to raise revenue for schools, wars, and other public projects without significantly increasing taxes. Today, the lottery is one of the most popular forms of gambling in the United States, with more than 90 percent of adults living in a state that has an operating lottery.

While the basic elements of lotteries vary considerably, all operate on the same principle: some form of public selection is combined with an element of chance to select a winner or winners. Typically, the lotteries involve writing names, numbers, or symbols on a ticket that is submitted for shuffling and possible inclusion in a drawing. Alternatively, the bettor may place money into an account that is matched by random number generators. Regardless of the type of lotteries, all must provide some mechanism for recording the identity of bettors and the amounts staked, as well as some way to identify whether or not a ticket has won.

When states adopt a lottery, they often legislate an exclusive monopoly for themselves; establish a state agency or public corporation to run the operation (as opposed to licensing a private firm in return for a share of the profits); and start operations with a modest number of relatively simple games. In order to expand revenues, the state progressively adds new games and features to its offerings.

Lottery proceeds are allocated in a variety of ways, depending on each state’s fiscal climate and political culture. The allocations are usually divided between education and general state funding, although some states also distribute a portion to social welfare programs. During 2006, Lottery profits totaled $17.1 billion in the fifty states plus the District of Columbia.

Many studies have indicated that the popularity of lotteries is linked to the degree to which they are perceived as benefiting a particular public good, such as education. The public-benefit argument is particularly effective in times of financial stress, when the specter of tax increases or cuts to state programs tends to dampen support for other alternatives.

Most states oversee the operations of their lotteries through a state board or commission, with enforcement of fraud and abuse responsibilities typically vested in a state attorney general’s office or in the state police. In addition, most states allow a variety of independent retailers to sell tickets. In fact, many states offer discounts to their own retailers to entice them to participate in the lottery. In addition, some state lotteries have partnered with companies such as sports franchises to create promotional games that feature popular products such as automobiles and household appliances. In these merchandising partnerships, lottery officials and the company benefit from brand exposure and joint advertising costs.
