In an increasingly competitive world, the best advice for jobseekers is to develop new skills. Education is a good way to develop skills -- and it may lead to better employment prospects and higher earnings. But opportunities for secure, lucrative careers also exist for workers who prefer to acquire skills on the job. This article uses data from the US Bureau of Labor Statistics (BLS) and the US Census Bureau to analyze how workers' education or training relates to their job prospects and earnings. The information is useful for learning about occupations and possible career options at various education levels. The first section of the article explains the methodology used. The second section looks at data and trends relating to the educational attainment of workers. BLS projects opportunities for new workers from two sources: new openings resulting from growth, and openings resulting from workers who leave an occupation and need to be replaced.
