The easiest way to accomplish this is to go to http://www.LRES.info and click on the community reports tab at the top of the page. Type in the zip's your questioning and all the info will be at your fingertips. Good luck!
First off - you might try this link for some general demographic information. I looked up Anderson Township, it should be easy to navigate around to other areas nearby.
This, or information from the census bureau is probably your best source of demographic information. Weigh the anecdotal info you might get from any Realtor against your own gut... and hard demo data like above.
But let me respond from a more "macro" viewpoint. I wrote a blog post in June, about the effect the Echo Boomer generation will have on housing demand. (see reference below). EchoBoomers are 80 million strong - 3 million more than the BabyBoomer generation. BabyBoomers led to a huge build-out to meet housing demand; and the rise in home prices during the 60s thru 80s. It's likely history will repeat itself with this new generation.
No doubt about it, the EchoBoomers are already flexing their muscles with the current uptick in home sales - first time buyers are driving the boat! A good number of EchoBoomers may well be holding back while the economy turns around over the next couple years... but that equates to pent-up demand over the longer term.
That's a roundabout way of answering your question. If you have a 5-10 year window, and you buy a newer home in an area with good schools, that is suitable for a family (3 bedrooms, 2 full baths minimum)... I think you'll be pleased with how quickly it sells.
And if you need any help finding that home, I hope you'll give me a call.
Basically, the price point for the area is going to draw a young single professional or a young professional couples with or without children at the lower end. The higher point of the range will most likely draw couples with children. The school district report card http://(www.ode.state.oh.us) is a good indicator to go by. 4 bedrooms are usually a key element to resale as are updated kitchens and baths. Wallpaper and borders are considered negatives for most people's tastes. A question you didn't ask, but should be considering-- of the sales, how many have finished basements versus unfinished bsmts.?
