that's a very reasonable and important point; it is a challenge to motivate happy people to assess their wellness level. So what I need is just to get this information without trying to motivate them much ;) As per my initial efforts to get some real sample data, that seems to be quite doable by household/street polls performed by either volunteers or paid buddies. Further plans include some extra methods to get this information but as for now self-assessment and some kind of polls seem to be feasible and be a reasonable way to get more or less balanced information.
