What is a Lottery?

Lottery is a process for allocating money or goods (or both) to people by chance. Some governments outlaw it, while others endorse it to the extent of organizing a national or state lottery and regulating its operations. The most common type of lottery is a drawing of numbers for a prize; it is also known as a raffle or a sweepstakes. Some lotteries offer one large prize while others distribute smaller prizes to many winners. The value of the prize varies, but it is usually less than that of an ordinary product or service sold by commercial companies.

There are two main reasons why states adopt lotteries. The first is that they need to generate income. This is a valid point, but it ignores the fact that state governments are already generating a great deal of income through other means, such as taxes.

The second reason is that lotteries attract people who would otherwise gamble illegally. In the past, this was a valid argument, but it now seems less so. Lotteries are not simply attracting people who would otherwise gamble illegally, they are creating whole new generations of gamblers.

In the US, a state usually legislates a monopoly for itself; establishes a state agency or public corporation to run it (or licenses a private firm in return for a share of profits); begins operations with a modest number of relatively simple games; and then progressively expands its operation as demand grows. In general, the state legislature and voters must approve a lottery before it can be established.
