Private employers in New Jersey added 30,900 jobs in December, the largest one-month gain since the current system of employment tracking began in 1990, the state Labor Department reported Thursday.
Economists say that cleaning up from Sandy and the start of rebuilding were factors, but there was strong growth in areas that seem to have been unaffected by the storm.
"Do you believe in miracles?" asked James Hughes, dean of the Bloustein School of Planning and Public Policy at Rutgers University. "It's kind of spectacular job growth for December."
But it comes with caveats.
The strong month capped a sluggish year and accounted for about two-thirds of the state's total job growth for 2012. Even with the new jobs, the unemployment rate was a stubbornly high 9.6 percent. That's the same as the rate initially reported for November. But on Thursday, November's rate was adjusted upward to 9.7 percent.
The unemployment rate remained nearly 2 points higher in New Jersey than the national December rate of 7.8 percent.
Also, New Jersey's public sector employment dipped by 700 for the month. But overall job growth for the month was still more than 30,000.

"New Jersey has 1.2 percent more jobs today than it did a year ago," said Patrick O'Keefe, director of economic research at J.H. Cohn. "That's better than going backward, but it's still not very robust."
O'Keefe said that at the current growth rate, it would take three more years for the state to get back to the number of jobs it had in December 2007, just before the Great Recession began taking its toll on jobs.
The December job growth came across all major private industry sectors. Construction added 4,300 at a time of year when employment in that industry would normally be dropping. The economists said that's linked to early post-Sandy rebuilding efforts.
Hughes also said some of the 2,300 additional financial sector jobs are related to storm recovery as insurance companies add staff and banks bring in additional loan officers.
Charles Steindel, chief economist for the state's Treasury Department, said the job growth came for a few reasons: December is usually a big hiring month because of holiday shopping and on top of that, Sandy suppressed hiring in November, when the economy was otherwise primed for growth.
"There was a normalization," he said. "People who weren't hired in November were hired in December."
The percentage of working-age people in New Jersey with jobs or looking for them continued to rise in December, up to 66.2 percent, the Labor Department reported, several points higher than the national rate. Those figures affect the jobless rate, because the government only counts as unemployed those actively searching for work. Steindel said that New Jersey's unemployment rate is artificially high because of the number of job-seekers.
A preliminary analysis shows that from December 2011 to December 2012, employment grew by 48,000 jobs, with the private sector accounting for more than 46,000. The Labor Department said that figure represents the largest over-the-year private sector increase in jobs since December 1999 to December 2000, when more than 64,000 jobs were added.
It will not be clear until March whether the major one-month growth can be sustained. The Labor Department does not release a monthly report in February.
