The unemployment rate fell to 3.9% in July

The US economy keeps on pumping out jobs.

The unemployment rate fell to 3.9% and the economy added 157,000 jobs in July, the Labor Department said Friday.

But workers’ paychecks grew tepidly from the previous month and are up just 2.7% compared to the same time last year.

“With inflation running at a roughly 2% rate, that means that there’s not a lot of financial wiggle room for many Americans,” said Mark Hamrick, Bankrate.com’s senior economic analyst. Economists will get another update on inflation next week when consumer and producer price indexes’ are released.

The hiring spree has continued as the economy expands. The economy grew at 4.1% during the second quarter, its fastest place in nearly four years.

In a statement on Wednesday, the Federal Reserve called the economy “strong.”

“Job gains have been strong, on average, in recent months, and the unemployment rate has stayed low,” the Fed said. “Household spending and business fixed investment have grown strongly.”

Although the July hiring number fell below economists’ expectations, the government revised the previous months’ job gains by an additional 59,000. With revisions, job gains have averaged 224,000 a month over the past three months.

So far this year, job growth has averaged 215,000 per month, above last year’s pace of 182,000, noted PNC chief economist Gus Faucher.

Last month, the manufacturing sector added 37,000 jobs. Economists were watching manufacturing closely for signs of a drag from the Trump administration’s escalation of trade tensions with China and allies.

“It appears to be that the strength of fiscal stimulus measures are outweighing any kind of effect of trade tensions,” said Josh Wright, chief economist at the software firm iCIMS.

The retail sector also added 7,000 jobs, despite 32,000 jobs lost in sporting goods, hobby, book, music and toy stores.
