@mysteryman,
There is a difference in scale between a county and a state. The population of PWC is just under 380,000 while the population of AZ is more than 6,500,000.
According to the US Census Bureau, PWC in VA is 69% white with an Hispanic or Latino population of 19%, while blacks make up 20%.
Hispanics seem to be prosperous in the county, owning 12% of the businesses.
A total of 16% of the population uses another language at home.
It should also be noted that 31% of the PWC population holds a bachelor's degree.
AZ is more white as a state than the Virginia area is as a county: 86.5% of the folks in AZ are white. About 1/3 are Hispanics, but, remember that Hispanic is not a racial designation according to the census bureau footnote on both pages and people are self-identified for census purposes. Blacks are scarce in AZ, accounting for less than 5% of the population.
Hispanics own only 9% of the AZ businesses.
About 1/4th of the residents speak a language other than English at home.
Overall, only 23% of Arizonians have a first college degree.
