U.S. added 192,000 private-sector jobs in Jan.

The U.S. economy added 192,000 private-sector jobs this month, according to the ADP National Employment Report issued Wednesday.

The job gains are from December to January, on a seasonally adjusted basis, and builds upon the 185,000 jobs that were created between November and December 2012, the report said. That projection was revised down by 30,000 jobs.

The bulk of the job growth took place in small businesses, which the payroll processing company defines as those with one to 49 employees. A total of 115,000 jobs were created by small businesses.

Medium businesses, which have between 50 and 499 workers, added 79,000 jobs. However, large businesses, which have at least 500 employees, lost 2,000 jobs, the report said.

Carlos A. Rodriguez, president and chief executive officer of ADP, said there have been an average of 183,000 job created each month, and he described the latest numbers as a positive sign.

“This is an encouraging sign of steady improvement in the job market.”

The latest state unemployment report showed some 30,000 jobs were added in New Jersey last summer.

But state Democrats have charged the growth isn’t taking place adequately, as the state’s unemployment rate has remained stubbornly above the national average in the high-9 percentile.
