Is Section 8 in high demand pretty much everywhere?

[Gary Dezoysa]

Greetings, I come from Southern California where section 8 housing is in high demand. However, I plan on moving to a cheaper area of the country where $30,000 houses in working-class areas can be found.

I'm not sure if I should be concerned about narrowing my list of choices by "section 8 demand" or not.  

Is the section 8 program in high demand virtually everywhere in the country, or is it something I need to dig into before I consider an area?
