Referencing this proposal on Area 51: http://area51.stackexchange.com/proposals/37195 and this post here: https://stats.stackexchange.com/questions/20788/what-is-the-income-distribution-in-the-u-s-in-1-increments
We have at least one mod (mbq) suggesting its a duplicate of CrossValidated (and thus would belong here) and IIRC comments to that effect from CV users and mods on the proposal before they got swept up by an Area 51 mod.
whuber then closed the question because its off topic.
So is it, or isn't it?
