Rural areas? Now the ball’s in MY court!
Personally, I rarely see much a difference in the cost of most retail goods. Some foods might be somewhat cheaper, especially locally grown fruits or vegetables, or possibly meat and dairy products.
Real estate is, of course, significantly cheaper. Construction costs may be fairly comparable (or even more expensive in the case of highly specialized structures) but they depreciate quickly. Furthermore, they’re sitting on very cheap dirt. The importance of the cost of real estate cannot be understated: for many households, housing costs can approach 50% of their net income.
Utilities may also be significantly cheaper. Rural areas often form “electric cooperatives” which are frequently non-profit in nature. Water and sewer may be provided by the local municipality at a fraction of their big-city counterparts, or in many cases water and sewer services are provided by wells and septic tanks. Phone services that might otherwise be more expensive may be subsidized through the “universal service charge.”
Sales taxes, at least in Oklahoma, are typically not significantly different between large cities and small towns. Income taxes 'round these here parts are only assessed by the state government, so there’s no difference there. BUT, property taxes may be wildly lower in rural areas. Total millages between 60 and 70 mills (based on an 11% assessed to market ratio) are common in rural areas… in the Tulsa and OKC areas, it’s more like 120 to 130 (and remember that these are higher rates on higher market values!)
Some locally provided services may also be significantly cheaper, though I’m trying to think of a good example of this… maybe rural lawyers or general practicioners.
Another money saver that’s been mentioned already (I believe) is just the fact that rural lifestyles are often a lot less expensive. You may think twice about going to see a movie if the nearest movie theater is 50 miles up the road! Theater prices in rural towns are also often much cheaper to boot… I think I paid $4.50 to see a first-run movie in McAlester a little while back.
Someone mentioned gas prices… if anything, gas prices in Oklahoma are typically significantly lower in urban areas as compared with the rural ones, at least in my fairly vast experience driving through po-dunk towns in this state (Slapout, OK anyone?)
Finally, the cost of living needs to be at least a little cheaper in rural America, considering how much lower rural income levels are.
