The Occupational Outlook Handbook provides comprehensive profiles of 275 popular careers, including predictions about demand. The new edition has just been published. It's free online or $20 in book form.
Jist, publisher of the book version, just sent me a press release summarizing what's new in this year's Occupational Outlook Handbook:
"Some occupations are now expected to grow considerably faster than was previously expected, notably those in the Finance and Insurance and Human Service clusters. Overall, however, projections for job growth now are a little less optimistic than two years ago, especially in the Manufacturing and Retail and Wholesale Sales and Service clusters. Job-growth forecasts also have been cut back, though to a lesser extent, for the high-flying Health Science and Education and Training clusters...The U.S. economy has shifted toward service industries such as health care and hospitality. As a result, more and more opportunities will be found in jobs that involve a lot of interpersonal contact, and chances to work alone will become more scarce."
