scientists, and big data engineers rank

emerging jobs

Trump wasn't in his office in Washington DC

data used in January 2017 jobs report, so for

exclude the first month of the year. But in the
remaining 11 monthly jobs reports, employers
added 1.84 million jobs, according to the
December jobs report released Friday.
