Chapter 12 - Great Plains and Prairies

Simi Valley and the Great Plains and Prairies share a common misconception.  Many people believe that the residents of both areas share the same ethnic background.

In reality, there are areas within the Great Plains and Prairies that are ethnically diverse, like Colorado and Winnipeg.  

Simi Valley is also more ethnically diverse than it gets credit for.  In fact, the white population in Simi Valley declined from 80% in 1990 to 73% in 2000.  At the same time, the Hispanic population in the city has increased from 12% to 17%.
