Chinatowns are moving from the city to suburbs in many US areas (according to articles) (largest, suburb)

Suburbs are where new Chinatowns are relocating to in many places

There are certainly lots of Chinese restaurants run by Chinese people in the Denver burbs. No specific "Chinatown" though. There's a huge Asian market in the Denver suburb of Broomfield.

Well yes, they're looking for places with cheap rent. My city has a "Little Saigon" along a commercial corridor on the southern border of the city, primarily commercial strip malls. There is a small, redeveloped "Chinatown" downtown, once the second largest on the west coast, and our Japantown was wiped out after World War II. The neighborhoods to the south have strong Chinese and Japanese populations but mostly they moved into the suburbs once racial exclusion covenants were done away with and housing discrimination became illegal. Because most of the houses and commercial spaces in western cities is in the suburbs, and aging suburbs are less attractive for new investors, they become places where those with little money can make a niche. In the process they may become more urban in function if not in form.

In Portland, the Chinatown that is downtown is just a shell of itself with a pretty gate. The actual Chinatown is now out on 82nd, called the Jade District. Though when it comes to other Asian foods, much of that can be found in anywhere in Portland, whether it be Thai, Korean, Vietnamese, or so on.
