This is an interesting story on New York's shrinking community of Cambodian Americans, who are moving elsewhere in the country for better opportunities and services: Little Cambodia, Growing Still Littler.
Data from the 2000 census shows that the city's Cambodian population decreased by 31 percent from 1990 to 2000. According to a census analysis by the Hmong Studies Internet Resource Center, the decline occurred while nearly all the country's other Cambodian communities were expanding.
They're moving to places like Long Beach, CA, Lowell, MA, and Minneapolis, where Cambodian cultural, religious and community centers are expanding and flourishing. And it's more than just donut shops.
