Lottery is a state-sanctioned game in which participants purchase tickets and hope to win prizes by drawing numbers or matched combinations of letters. The prizes are usually cash, goods, or services. State-run lotteries are very common and generally have broad public support.
Many states sponsor lottery games as a source of public revenue, with proceeds often earmarked for a particular cause. These are called “public-purpose” lotteries. They tend to generate broad public support, especially when they are perceived as a good use of taxpayer funds. Public-purpose lotteries are particularly popular in times of economic stress, such as when a state may need to raise taxes or cut public programs.
In the United States, public-purpose lotteries are typically run by state agencies or corporations, and are designed to be unbiased. In other words, the chances of winning are roughly the same for everyone who plays. This is demonstrated in the graph below, which shows a scatterplot of lottery results where each cell represents an application and the color indicates how many times that application has been awarded its position in a given draw.
In recent years, state lotteries have begun to rely on two main messages in their advertising. One is that playing the lottery is fun and the other is that playing the lottery is a great way to get rich. This is a subtle and misleading message that obscures the regressivity of the lottery. It also gives people the idea that the lottery is a harmless form of gambling when, in fact, it is an extremely risky investment and the odds are stacked against them.
