U.S. private-sector employment rose by 188,000 in June, seasonally adjusted, according to the national employment report released today by Automatic Data Processing Inc. (NASD: ADP). May’s employment growth was revised downward to 134,000 from the initially reported 135,000.

“The job market continues to gracefully navigate through the strongly blowing fiscal headwinds,” said Mark Zandi, chief economist of Moody’s Analytics, which produces the report for ADP. “Healthcare reform does not appear to be significantly hampering job growth, at least not so far. Job gains are broad based across industries and businesses of all sizes.”

The service-providing sector added a total of 161,000 jobs in June, its largest increase since February and greater than the sector’s average gain of 146,000 through the first five months of the year. Trade/transportation/utilities added the most jobs in June with 43,000 — its strongest increase since the start of 2013. Professional/business services grew by 40,000 jobs, and financial activities added 13,000 jobs, nearly double the average monthly pace through the first five months of the year.

The goods-producing sector added 27,000 jobs in June, its largest increase in four months. Construction added 21,000 jobs in June, its biggest gain since January, while manufacturers added 1,000 jobs following a two-month decline.

Small businesses, those with fewer than 50 workers, added 84,000 jobs in June. Large business, those with 500 or more workers, gained 49,000 jobs. Midsize businesses added 55,000 jobs.

The report is derived from a sample of ADP data from approximately 416,000 U.S. business clients representing 24 million U.S. employees. Methodology utilizes ADP payroll data, U.S. Bureau of Labor Statistics employment data, and the Philadelphia Federal Reserve Bank’s Aruoba-Diebold-Scotti Business Conditions Index.
