Total employment in the U.S. economy is projected to grow to 161 million, or 10.8 percent, over the 2012–2022 decade and add 15.6 million jobs to the 2012 employment level of 145.4 million. Of the 818 occupations for which the Bureau of Labor Statistics (BLS) produces and publishes projections data, 667 are projected to add jobs during the 2012–2022 period. Some of the fastest projected growth will occur in the healthcare, healthcare support, construction, and personal care fields. Together, these four occupational groups are expected to account for more than 5.3 million new jobs by 2022, about one-third of the total employment growth.
