I have completed several high end properties in the last year for my personal portfolio, and have shifted gears back into the middle/lower income area as this demographic is having a hard time finding quality homes that are reasonably prices.  

Is there a transition happening from an age demographic?  

I live there all my life no the demographics and have owned many houses and flipped many houses there.  

The exception would be if your serving a market that caters to a student target demographic, such as near a college or senior housing target market.

In addition, I like www.City-data.com they have a lot of demographic and crime data, you just have to sort through some ads. 

I know the demographics and employment outlook for much of Orlando is rosy but I'm more interested in the Disney area,specifically.

What are the demographics of your typical renter in the area?

From a marketing point-of-view, I would want to know exactly who my target demographic is for that exact neighborhood. 

I'd say look at demographics (change in population, employment, etc.) in those areas and, importantly, drive through them yourself, to see what you like and what's convenient for you.Also as I've recommended recently in other threads, be sure to check out the finances of any city/town you're planning to buy in, including current and historical changes in municipal bond ratings (Moody's, Fitch, etc.).

What are the demographics for the population increase?
