A casino, also known as a gambling house or a gaming hall, is an establishment for certain types of gambling. Its popularity is increasing as more states legalize it, despite its detrimental effects on local property values and the number of people who become addicted to gambling.
In America casinos are found in cities with a large tourist population, such as Las Vegas, Reno, and Atlantic City. They may also be located on American Indian reservations, which are not subject to state antigambling statutes. Some casinos are part of resorts or hotels, and offer a variety of other entertainment options, such as concerts and dining. Casinos are also a significant source of income for some states.
Various studies have shown that about 13.5% of gamblers win money at casinos. In contrast, lottery winnings average about 15% of the total amount wagered. The profitability of a casino depends on the games offered and the amount of money that is wagered. In some cases, the house edge (the advantage to the casino) is less than one percent, while in others it is much higher.
The casino business has been expanding around the world, and it is now a major industry in many countries. Its economic significance is growing because it provides jobs, taxes, and profits for governments and private businesses. It is estimated that the global market for casino gambling will increase by about 6% each year, to $90 billion by 2020.
