What is a Lottery?

A lottery is a system for allocating prizes, usually money, by chance. People pay a small fee to enter the lottery, and the winnings are determined by a random drawing. The lottery is a common method of allocating resources in society, and there are many different kinds. Examples of this include a lottery for units in subsidized housing, or a lottery to determine kindergarten placements. Lotteries can also be used to raise money for a state or other entity.

People spend upward of $100 billion on lottery tickets in the US each year, making it one of the most popular forms of gambling. States promote lotteries by telling people they are a good way to raise revenue for things like public education, health and welfare, and infrastructure. But how much of that revenue actually goes to those specific ends, and whether it’s worth the trade-offs to people losing a large portion of their disposable income, is open to debate.

I’ve talked to a lot of people who play the lottery, often for years, spending $50 or $100 a week on tickets. They tell me that they value the hope that the ticket gives them — even though they know it’s irrational and mathematically impossible.

The idea of a lottery is as old as human civilization itself. The Bible records that the Lord instructed Moses to distribute land by lot, and in ancient Rome, emperors gave away property and slaves through lotteries at Saturnalian feasts. The first recorded public lotteries were in the Low Countries in the 15th century, and they raised funds to build town fortifications and to help poor people.
