All of the NIGC’s administrative regions experienced positive growth, contributing to the highest ever revenue in Indian gaming history.
Portland showed the highest increase, with gaming revenue of $3.7m, an 8% rise, followed by Oklahoma City at $2.5m, a 7% rise.
Total Indian gaming revenue has risen 27% since 2009.
Kathryn Isom-Clause, Vice Chair of the NIGC, said: "These numbers reaffirm the industry’s health as a stable economic driver for Indian Country."
Edward Simermeyer, Associate Commissioner of the NIGC, said: "The annual GGR tells a positive story about Indian gaming’s economic success and the industry’s ongoing contribution to a strong economy.
"It also tells the story of how collaboration among tribes, industry and the regulatory communities can build a strong reputation for reliability and integrity in the GGR calculation."
