As stated, I'm no statistician, but here's what I got. I'm sure some of you would be insulted if I listed job by job, how, out of ignorance, I classified you. So I won't tell you and thereby save you the insult. From a government contractor, this will have to suffice:
34 - White Collar
38 - Blue Collar
5 - Green Collar
14 - Self employed
5 - Retirees
8 - Mechanics (as I read through the thread I would have sworn there were more.)
11 - Engineers
9 - Pro-Tree Guys (What are they doing on a sight dedicated to Arboriculture?)
And 1 - Domestic Engineer.
If the numbers don't add up it's because a self employed Mechanic fills a slot as blue collar, self employed and a mechanic.
