Government Executive has a piece on the Bureau of Labor Statistics predictions of job growth by occupation over the next 10 years. It's interesting, but BLS projects that jobs in agriculture will shrink (-3.4 percent), the only occupation for which that's true. However, the piece revisits the predictions from 2002. It turns out they had predicted a 2 percent drop in ag jobs, but the reality was a 7.4 percent increase!
That might tie into the increase the Ag census has seen in the number of farms, which in turn might be driven by the popularity of organic and niche farm products, otherwise known as the food movement. I can see it growing, particularly as Whole Foods (we own shares) does more linking with local producers and moves into smaller cities, like Boise, Idaho.
