Q. Where can I find information about different career fields and their job demand?
Check out the Library's research guide on career information at http://library.uhd.edu/career/. Go to the "Research Careers" tab and then find the link for US Department of Labor Occupational Outlook Handbook. You can search or browse the handbook online for the information you need.
You should also contact UHD's Career Development Center for information on job markets.
