WASHINGTON — The addition of 163,000 jobs in July follows three months of sluggish hiring and shows that the US economy is likely resilient enough to keep growing at a modest pace.

Employers have added an average of 151,000 jobs a month this year, although that’s not been enough to drive down the unemployment rate, which ticked up to 8.3 per cent from 8.2 per cent in June.

The Labour Department’s July employment report did little to settle the political debate about the economy, with Obama administration officials and Republican challenger Mitt Romney seizing on the latest data to bolster their campaigns with less than four months to go until Election Day.

President Barack Obama, speaking at the White House, noted the job growth but added, “We still have too many folks out there who are looking for work.”

Stronger job creation could help Obama’s re-election hopes in November. Still, the unemployment rate has been above 8 percent since his first month in office — the longest stretch on record. No president since World War II has faced re-election with unemployment over eight per cent.

White House economist Alan Krueger said the job gain shows the economy is still recovering. Overall, the economy has added 4.5 million private-sector jobs in the past 29 months, he said.

But Romney, the presumptive Republican presidential nominee, focused on the increase in unemployment.

“We’ve now gone 42 consecutive months with the unemployment rate above 8 percent,” Romney said in a statement. “Middle-class Americans deserve better, and I believe America can do better.”

Before Friday’s report, economists were increasingly worried that a slowdown in hiring and growth from April through June could get worse and develop into something more long-lasting. Now they are breathing a little easier.

“After a string of disappointing economic reports … we’ll certainly take it,” said James Marple, senior economist at TD Economics.

Stocks rose sharply in early trading. The Dow Jones industrial average added 243 points to 13,122, while the broader Standard & Poor’s 500 index rose 27 points to 1,392.

The government uses two surveys to measure employment trends. Hiring is measured through a survey of businesses. The unemployment rate comes from a survey of households and is calculated by dividing the number of people who say they are unemployed by the size of the labor force. In July, more people said they were unemployed, while the size of the labor force shrank.

Economists say the business survey is more reliable.

A better outlook on hiring could make the Federal Reserve reluctant to take more action to spur growth. The Fed, which ended a two-day policy meeting Wednesday, signaled in a statement a growing inclination to take further steps if hiring doesn’t pick up.

But some economists say the job gains need to be greater for the Fed to hold off.

Paul Ashworth, senior U.S. economist for Capital Economics, said July’s job gains were a “vast improvement” over the past four months. Still, they were well below the average 252,000 jobs a month added from December through February.

“It also isn’t strong enough to drive the unemployment rate lower, which is what the Fed really wants to see. So, on balance, we doubt this would be enough to persuade the Fed to hold fire in September,” Ashworth said.

The economy remains weak more than three years after economists declared the recession had ended in June 2009. Growth slowed to an annual rate of 1.5 per cent in the April-June quarter, down from two per cent in the first quarter and 4.1 per cent in the final three months of 2011.

US growth could also be hampered further by a weaker global economy. Europe’s financial crisis has pushed much of that region into a recession, while growth in China, India and Brazil has slowed.

Worries have also intensified that the U.S. economy will fall off a “fiscal cliff” at the end of the year. That’s when tax increases and deep spending cuts will take effect unless Congress reaches a budget deal. A recession could follow, Fed Chairman Ben Bernanke has warned.

Those concerns provide employers “plenty of reasons for caution,” said Nigel Gault, chief US economist at IHS Global Insight. He expects monthly job gains will only be between 100,000 and 150,000 in the second half of this year.

The July job gains were broad-based. Manufacturing added 25,000 jobs, the most since March. Restaurants and bars added 29,000. Temporary help services added 14,100 jobs. Retailers hired 7,000 more workers. Education and health services gained 38,000. Governments cut 9,000 positions.

Average hourly wages also increased by two cents to $23.52 an hour. Over the past year wages have increased 1.7 per cent — matching the rate of inflation.
