Lottery is a form of gambling in which numbered tickets are sold and prizes, such as cash or goods, are awarded to the winners. It is one of the most popular forms of gambling. Many people play the lottery for recreation or as a means of raising money. Some states have laws against it, while others regulate it. The first European lotteries in the modern sense of the word were probably held in 15th-century Burgundy and Flanders with towns attempting to raise money to fortify their defenses or aid the poor. The earliest public lottery to award money prizes was the ventura in 1476 in the Italian city-state of Modena under the auspices of the ruling d’Este family (see House of Este).
Lotteries were also very popular in colonial America where they helped finance public and private projects such as roads, wharves, libraries, colleges, churches, and canals. They were used to fund the founding of Harvard and Yale, and George Washington sponsored a lottery in 1768 to raise money for constructing a road across the Blue Ridge Mountains.
Lotteries have been criticized for being addictive and often result in financial ruin for the winners, as well as for being an unequal form of gambling. The people who win the biggest jackpots tend to have the least disposable income, which is why lottery games are regressive. People in the 21st through 60th percentile of income spend the most on tickets, but their disposable income is lower than that of those at the top of the distribution.
