State jobless rate up for first time since July 2012
Nonfarm employment fell by 1,300 jobs, with losses in government as well as in professional and business services, information, manufacturing, and construction, data show.
The jobless rate was up from 7.1 percent in February, though down from 8.7 percent in March 2013.
New Jersey has regained 121,400 private jobs since the recession's low point in February 2010 - about half of those lost.
"We continue to anticipate that job growth should kick into higher gear," Charles Steindel, chief economist for the New Jersey Treasury Department, said in a statement.
A positive development, Steindel said, was that the number of unemployment claims received in recent weeks was among the lowest in several years.
The national jobless rate in March was 6.7 percent.
