From the projections overview:
Total employment is expected to increase by 20.5 million jobs from 2010 to 2020, with 88 percent of detailed occupations projected to experience employment growth. Industries and occupations related to health care, personal care and social assistance, and construction are projected to have the fastest job growth between 2010 and 2020. Jobs requiring a master’s degree are expected to grow the fastest, while those requiring a high school diploma will experience the slowest growth over the 2010-20 timeframe. Slower population growth and a decreasing overall labor force participation rate are expected to lead to slower civilian labor force growth.
Job openings result from the relationship that exists among the population, the labor force, and the demand for goods and services. The population restricts the size of the labor force, which consists of working individuals and those looking for work. The size and productivity of the labor force limits the quantity of goods and services that can be produced. In addition, changes in the demand for goods and services influence which industries expand or contract. Industries respond by hiring the workers necessary to produce goods and provide services. However, improvements in technology and productivity, changes in which occupations perform certain tasks, and changes in the supply of workers all affect which occupations will be employed by those industries. Examining past and present changes in these relationships in order to project future shifts is the foundation of the Employment Projections program of the Bureau of Labor Statistics (BLS, the Bureau). This page presents highlights of BLS population, labor force, and occupational and industry employment projections for 2010-2020.
