Just a recommendation if you need info for your clients. This place for corporate anthropology has somehow rounded up info on over 10 million people and digitized huge amounts of info about those people into a virtual world. They say it is like 2nd Life or Sim City, but based on real people. They give great discounts for individuals, I know because I use their info. This won't put me out of a job to share a resource and it really helps to have this sort of predictive power as part of my toolkit. Good luck all. Edit to add the company name, Avatar Analytics. Great advice if I don't include where to get help. Sorry.
