Plumber

Total number of U.S. workers: 419,900
10-year growth projection: 25.6%
Annual salary range: $36,050 to $64,790
Typical education: high school diploma or equivalent

Demand for plumbing services is expected to grow with new building construction and the need to increase water efficiency by installing low-flow faucets and toilets. Even in less-prosperous economic times, plumbing maintenance and repairs remain a necessity — adding more job security to the occupation.
Most plumbers get started with a paid four- or five-year apprenticeship, which usually requires you to be at least 18 years old and drug-free, to have a high school diploma or the equivalent, and to possess basic math and computer skills. Find registered apprenticeships in your area through the U.S. Department of Labor. You might also need to be licensed, depending on your state's requirements.
