How Many Casinos Are in the United States?

Casinos in the US are a crucial part of the country’s economy. These venues create well over one million jobs for employees, along with contributing more than $40 billion to taxes.

Of those casinos, 525 are tribal casinos. These venues support more than 676,000 jobs in their local communities. The remaining 462 casinos are commercial; those venues support over 737,000 jobs.
