Of the 3.8 million job openings in the U.S. in May 2013, 645,000 were in the accommodations and food services sector -- the highest number of openings in any sector, according to data from the JOLTS (Job Openings and Labor Turnover) report released by the U.S. Bureau of Labor Statistics this week.

The accommodations and food services sector had not only the highest number of job openings but also the highest job openings rate -- that is, the number of job openings as a percentage of all the jobs that exist in that sector. The job openings rate is a pretty good indicator of how quickly a sector is expanding. A higher rate indicates that sector is expanding quickly, while a lower rate indicates slow growth.

Other sectors with a high job openings rate in May were professional & business services, arts, entertainment & recreation, and other services.

But sectors like manufacturing, construction, wholesale trade had low job openings rates, indicating slower growth.

While services-related sectors are expanding the fastest, industry sectors more involved with making things are experiencing slower growth.

Of all the sectors described in the report, the one with the lowest job openings rate was the federal government.

Here’s an infographic that charts out where each sector stands in terms of job openings and job openings rates:
