 Buddhism is still overwhelmingly present in East Asia and Southeast Asia: (China alone -- with only 18.2% of its population defined as Buddhist -- had over 244 million in the last census). Buddhism is the majority religion in Cambodia, Thailand, Myanmar, Bhutan, Sri Lanka, Japan, Laos, and Mongolia. There are significant numbers of adherents in Nepal, South Korea, Vietnam, China, and Malaysia. The United States has almost four million followers. Even in the closed society of North Korea, there are about 400,000 followers.
