Hi Brendan. I think the idea of the survey is a very interesting one. If you're going ahead, I'd suggest you might consider the following as possibilities. You could tweak them as you saw fit.
In Emploment, I'd have a tick box for Director, Management, Self employed, part-time etc., too. Also, a tick box for having a partner who works/doesn't work.
As a sub section of Unemployed, you might have boxes to indicate if the member became unemployed in the past 3 months, 6 months, etc.
Under Annual Income, I'd break it down to jumps of €20k up to €100k and maybe jumps of €50k after that and have a top one of maybe €250k+. I think having one box only for less than €100k would be fairly meaningless. And maybe you could have a starting point of less than €30k.
Something I'd like surveyed also if I was doing a survey (and it might be of little use to you) is the county each member lives in, with a box also for those AAM members who live abroad.
With regard to which party we might vote for next time round, I'd put a box for Independent/Other as well, as I feel that quite a few people will vote with local issues or vested interests in mind.
And finally, a question. Who in AAM would be privy to the information supplied by members? To expand the point, many posters enjoy being able to do so annonomously but, nonetheless, would be very happy, I'm sure, to take part in the suggested survey. I think that you, for example, would have to have access to the information yourself but I don't think that a lot of members would be very happy if the information was shared with others, e.g., Moderators.
Best of luck with it.
