ethnoburb
A particular area within an MSA but outside the central city where a particular ethnic group (nearly always an immigrant group) has decided to settle.
An ethnoburb is a suburban residential and business area in North America with a notable cluster of a particular ethnic minority population. The term was first coined in 1997 by Dr. Wei Li, then assistant professor of Geography and Asian American Studies at the University of Connecticut, in a paper examining the suburban Chinese population in Los Angeles (County,) California.1 Ethnoburbs emerge for a variety on reasons, in combination or as separate entities. These include significant changes in world politics and economy, policy changes in the United States' national policies, and demographic shifts in individual or in local connecting neighborhoods. These communities have substantial external connections to the globalised mainstream economy, leading to higher socioeconomic levels in its residents. An ethnoburb functions as a social hub and a place where immigrants may work and do business within their own networks. The formation of ethnoburbs also have an effect on the cultural and political characteristics of a city. In (MSA)s such as the San Francisco Bay Area, Vancouver, and Toronto, and in the San Gabriel Valley in California, for example, Chinese immigrants have built large houses and malls catering to Chinese businesses, changing the landscape of these and a significant number of smaller communities throughout the USA
