One source you can use is the bureau of labor statistics website.  I put it at the bottom.  It has a list of all the jobs (look in the index site).  Within that site it can tell you the nature of that type of work, the working conditions, job outlook, employment, and related occupations.\nThere is also an online occupational outlook quarterly and employment projections.\n\nHope these help you out!

I think that you can find most of that at http://www.nationmaster.com/. I use it when I need economic and energy statistics by country. I wish you luck finding your data!

I don't think so.  In a lot of ways, it's a left-over stat from when people mostly had 'traditional' 9-5 in the factory or office jobs.  It has the problems that you pointed out, and I think it also doesn't capture the complexity of modern work.  So many people work part time, temp or contract jobs and aren't counted at all

This is an interesting question. The census bureau's website would probably be the best place to start. I do not know if they have all of their stats posted from decades past.

Here is a nice site for you to look at.  It is for a large union that include many different workers from different fields.  Good luck.
