Official lottery is a form of gambling in which participants purchase tickets for a draw to determine the winner. Prizes may be cash or goods. The lottery is a popular source of public finance for many countries. Lotteries are most often run by state governments, although some are privately operated. Historically, the lottery has been used to fund a variety of public works and social programs. These include canals, roads, churches, schools, colleges, and other public services. In colonial America, lotteries also financed the construction of private ventures, such as colleges, libraries, and hospitals.

States have been able to expand their array of social safety nets in the immediate post-World War II period because they could sell lotteries and raise money without the kind of regressive taxes that would have disproportionately burdened the poorer members of society. But it’s been a brittle arrangement and it began to break down after the Vietnam War, and then again with the onset of inflation.

The prizes of lotteries are usually a fixed percentage of the total ticket sales, with the remainder being allocated for expenses and profits. Some lotteries organize games with large geographical footprints, serving as de facto national lotteries.
