WASHINGTON — U.S. businesses added a solid 183,000 jobs in February, a private survey found, a sign that companies are continuing to hire even as economic growth is likely slowing.

Payroll processor ADP said Wednesday that last month’s job gains were down from the 300,000 added in January, a figure that was revised up sharply from 213,000. It was also below last year’s average monthly gain of about 235,000.

Hiring occurred across all major industries tracked by ADP, including professional and business services, which includes high-paying fields such as accounting and engineering, and which gained 49,000 jobs. Education and health care added 37,000. Construction gained 25,000 jobs and manufacturing 17,000.

Mark Zandi, chief economist at Moody’s Analytics, a forecasting firm that compiles the ADP data, said that hiring slowed a bit because the economy is cooling. Still, he expects companies to keep adding jobs because growth will likely recover from the first-quarter slowdown.
