The lottery is an arrangement in which prizes are allocated to persons by a process that relies wholly on chance. This is contrasted with a system in which prize allocation is based on skill, knowledge or other factors.

Lottery is the most common method of distributing large sums of money. It is popular in many countries and has been used for centuries to determine fates, ranging from the winner of a sports competition to the winner of a state election. It is a form of gambling and as such must be regulated by law.

It has been suggested that the word “lottery” derives from Middle Dutch loterie, a compound of Old Dutch lotte, meaning ‘fate’ or ‘choice,’ and Old French loterie, literally “action of drawing lots.” The casting of lots for determining fortunes or other outcomes has a long record in human history (there are several instances of this in the Bible). The use of lotteries to distribute public funds has been recorded since medieval times.

The popularity of state-run lotteries has often been linked to a perceived or actual need for government revenue, especially in times of financial stress. However, studies have shown that this connection is tenuous and that the objective fiscal condition of a state has little or no impact on the decision to enact a lottery. Furthermore, studies have also shown that the majority of lottery players and ticket sales come from middle-income neighborhoods. In addition, these players tend to spend far less of their incomes than those from high-income neighborhoods.
