I think it depends on who you get tested with. If you do it with 23andme or ftdna, they give you the raw results and you can compare them to other raw results or upload them to gedmatch.com and compare with people there. I don't believe that ancestry.com gives you your raw results. Within each of these company's databases you can compare results with others who have tested with the same company. I haven't done any of this yet--it's just what I've read.
