This metropolitan area is the largest in the country, and therefore the people are very spread out. Without one main centralized city, different ethnic groups cluster in smaller cities and towns.

The population of the Inland Empire continues to increase, and as the area becomes more and more demographically diverse, the foreign-born population will continue to grow at an exponential rate.
