You might not need a bachelor's degree to tap into some of the country's fastest growing occupations, but some construction skills and health care know-how sure would help.

Why? Because it's the medical and construction industries that appear likely to provide those without a college education the greatest job opportunities between 2010 and 2020, according to occupational expert Laurence Shatkin, Ph.D., author of 300 Best Jobs Without a Four-Year Degree.

Helper or apprenticeship jobs, such as carpenters and plumbers, may see particularly substantial job growth. Using Bureau of Labor Statistics data, The Huffington Post found in a separate study that temporary help services are one of the fastest growing job markets, increasing nearly 45 percent since 2009.

The health care industry is also expected to experience significant growth in the coming years, primarily due to an aging baby boomer population. Job listings for pharmacy technicians alone have grown 43 percent so far this year, according to a September study from CareerBuilder.com. Go get 'em, kids.
