Gambling rates among Asians are higher than those of any other ethnicity in the United States, according to psychiatrist Dr. Tim Fong, co-director of UCLA’s Gambling Studies Program. “We did a survey a few years back, and at any given time, 35 percent of people in the casinos we visited were Asians,” even though Asians constitute only 14 percent of the state's population, Fong said. Fong said gambling rates are highest among Chinese, followed by Koreans and Filipinos.
