The Massachusetts unemployment rate held steady at 6.6 percent in November, putting an end to a four-month streak of increases, and keeping jobless numbers well below the national average of 7.7 percent.

About 1,100 jobs were lost last month, the state Executive Office of Labor and Workforce Development said Thursday, but year-over-year numbers showed the ranks of the employed have grown by 46,600. That increase was partially attributable to a revision of the October figures — 11,900 jobs were added to the economy instead of the 7,900 previously recorded, officials said.

Alan Clayton-Matthews, a Northeastern University economist, said the net job gains made in Massachusetts over the last few months were surprising given how the US economy sputtered in the third quarter. The tepid performance was blamed on the effects of Europe’s recession and a slowdown in Asia and other emerging markets.

“I was expecting a fourth quarter where we would see virtually no employment growth, [but] we’re actually having moderate growth,” Clayton-Matthews said.
