SAN JOSE — Easing concerns about a possible slowdown, the Bay Area gained more than 13,000 jobs in October, indicating the region’s economic boom appears back on track.

The hiring surge was distributed throughout the area, with the biggest gains in the South Bay, the East Bay and the San Francisco-San Mateo County region, the state’s Employment Development Department said Friday.

“This sets aside the fears that some of the job trends in recent months were pointing to a permanent slowdown,” said Stephen Levy, director of the Palo Alto-based Center for Continuing Study of the California Economy. “August and September were false scares.”

All told, the Bay Area added 13,100 jobs last month, according to preliminary figures released Friday. That’s well ahead of the relatively small job increases of 2,300 in August and 1,400 in September. The region saw robust growth in July, with an increase of 25,200 jobs.

“California’s tech centers posted the largest gains,” said Mark Vitner, senior economist with San Francisco-based Wells Fargo Bank. “The largest payroll gains in California were registered in the Bay Area.”

Santa Clara County gained 4,800 jobs, the East Bay added 4,200 and the San Francisco-San Mateo area gained 3,400, according to seasonally adjusted figures from the EDD and Beacon Economics.

“Growth is continuing, but a more modest pace,” said Jon Haveman, chief economist with San Rafael-based Marin Economic Consulting. “This is a slower pace of job gains, but the growth that we had seen before just couldn’t be sustained indefinitely.”

California added 31,200 jobs in October, labor officials reported.

The statewide jobless rate was 5.5 percent, unchanged from September.

“California numbers continue to show that the strong job gains in California have not slowed for now,” said Michael Bernick, a former director of the state EDD and a fellow with the Milken Institute.

During the 12 months that ended in October, the state added 389,500 jobs. That equates to an annual job growth of 2.4 percent.

“At this point in the economic cycle, the state is effectively at full employment, so the pace of job gains is somewhat tempered compared to a year ago,” said Robert Kleinhenz, executive director of economic research with Beacon Economics. “That said, the leading sectors of the state continue to add jobs at an impressive rate.”

Measured by multiple benchmarks, the Bay Area continues to lead California in job creation.

The Bay Area accounted for 42 percent of all jobs created in California during October. Over the last 12 months, the Bay Area has produced 27 percent of all the positions added statewide.

What’s more, over the one-year period that ended in October, the Bay Area job market grew 2.8 percent, ahead of the 2.4 percent annual pace for California and the 1.7 percent for the United States.

Santa Clara County’s job market outpaced the other major urban centers in the region and the Bay Area as a whole. The South Bay posted an annual gain of 3.3 percent, ahead of the 2.7 percent annual gain in total jobs for both the East Bay and the San Francisco-San Mateo region.

During much of 2013, 2014 and 2015, Santa Clara County and the San Francisco-San Mateo area had posted job gains of 4 percent on a regular basis, a pace economists deemed unsustainable. And jobs in Santa Clara County on occasion had even grown by an eye-popping annual rate of 5 percent.

“Growth rates have come back to Earth in the Bay Area,” Haveman said.

The tech sector in particular posted strong gains in October, according to a Beacon Economics analysis of the EDD report.

“We were worried about tech slowing down earlier in the year, but tech seems to be fine now,” Vitner said.

Tech companies added 1,900 jobs in Santa Clara County, 1,400 in the East Bay and 900 in the San Francisco-San Mateo region.

Leisure and hospitality jobs were robust. Hotels and restaurants added 2,400 jobs in San Francisco-San Mateo, 700 in the East Bay and 600 in Santa Clara County, the Beacon analysis showed.

Health care employers added 1,100 jobs in the East Bay and 1,000 in Santa Clara County.

Manufacturing and retail experienced a mixed bag in October. Manufacturers added 1,500 jobs in Santa Clara County but slashed 1,800 jobs in the East Bay. Retail added 1,600 jobs in Santa Clara County but the San Francisco-San Mateo area lost 400 retail jobs, according to Beacon’s assessment of the EDD figures.

“The Bay Area outlook is good, the momentum is continuing,” said Sung Won Sohn, an economics professor with CSU Channel Islands. “We were concerned over the summer about a slowdown in the Bay Area. But the momentum for the Bay Area is definitely forward.”
