General market forces are favorable right now. The large number of foreclosures has altered the market for rental properties as well. There are so many such properties on the market that prices are low. You can pick up an investment property quite cheaply (though it will likely need a lot of work).
Furthermore, those people who got foreclosed on have now become renters, so there are lots of potential tenants. The high number of properties would tend to lower rents (high supply), while the high number of tenants would tend to raise them (high demand). Mostly these factors have balanced out, and rents are generally fairly stable (or declining slightly).
It is tough be an absentee landlord though (if that is what you're planning), particularly of lower-end properties. I get a lot of such inquiries through my web site, from all over the country. Some have quite unrealistic expectations about what it takes to invest successfully. (It is not easy!)
Since I am in this for the long haul, and don't wish to rush people into purchases they will regret, I try to make sure they are aware of the issues they will confront. (Unfortunately for me in the *short-term*, this often scares them off :-)
Generally people either relocate, or have local partners who help them with management (perhaps family, though I've seen that go badly wrong!), or buy higher-end properties and hire a property management company. If you can afford, say, a 10- or 12-unit commercial property (which can be had in some areas for $250K or so), you can have that professionally managed and do quite well.
However, buying low-end property that needs work and trying to manage it exclusively from long-distance is unlikely to succeed.
As for finding data on demogrphics, it's all over the place! hellometro is another such portal. Trulia has some of this data.
http://realestate.yahoo.com/neighborhoods is another. ZipSkinny is yet another. There are tons of sites (don't forget Wikipedia).
Hope this helps! Let me know if you want to see specific listings.
