there are two big problems here. the first one is that you are asking people on a bitcoin forum. so you will get a better percentages because in most cases people in bitcoin tell others about it and others may get in it. so we usually have more friends owning bitcoin than others. but you can't make any conclusion based on that because your selection process was flawed.
and second one is already mentioned, people are usually reluctant to reveal that much about themselves (where they live, if they have bitcoin,...) in public like this.
