The number of Americans applying for unemployment benefits edged higher last week to 745,000, a sign that many employers continue to cut jobs despite a drop in confirmed viral infections and evidence that the overall economy is improving.

Thursday’s report from the Labor Department showed that jobless claims rose by 9,000 from the previous week. Though the pace of layoffs has eased since the year began, they remain high by historical standards. Before the virus flattened the U.S. economy a year ago, applications for unemployment aid had never topped 700,000 in any week, even during the Great Recession.

All told, 4.3 million Americans are receiving traditional state unemployment benefits. Counting supplemental federal unemployment programs that were established to soften the economic damage from the virus, an estimated 18 million people are collecting some form of jobless aid.

In Texas, applications for benefits surged by nearly 18,000 in the aftermath of freezing weather and power outages. And jobless claims rose by more than 17,000 in Ohio, where the weekly totals have been thrown off by potentially fraudulent claims.

Restrictions on businesses and the reluctance of many Americans to shop, travel, dine out or attend mass events have weighed persistently on the job market. Job growth averaged a meager 29,000 a month from November through January, and the nation still has nearly 10 million fewer jobs than it did in February 2020. Though the unemployment rate was 6.3% in January, a broader measure that includes people who have given up on their job searches is closer to 10%.

“Hundreds of thousands of Americans are continuing to struggle in this economy,” White House press secretary Jen Psaki told reporters Thursday. “We can’t get numb to what this represents. These are moms and dads, friends and neighbors, who will now have to worry about how they’ll support families, put food on the table and make ends meet in the midst of the pandemic.”

Psaki urged Congress to move quickly to pass President Joe Biden’s $1.9 trillion relief package, which, among other things, would provide $1,400 checks to most U.S. households.

The data firm Womply reports that 64% of movie theaters and other entertainment venues, 40% of bars and 34% of hair salons and beauty shops are closed. And on Wednesday, the Federal Reserve reported that across the country, “overall conditions in the leisure and hospitality sector continued to be restrained by ongoing COVID-19 restrictions.”

“The source of all labor market damage continues to be COVID-19,” said AnnElizabeth Konkel, economist at the Indeed Hiring Lab. “Increased vaccine distribution is promising, since the public health situation must improve for there to be a full economic recovery. When we completely return to ‘normal’ is still unknown.”

On Friday, though, economists have forecast that the government will report a strong job gain for February of near 200,000, which would raise hopes that layoffs will slow. Optimism is rising that increasing vaccinations and a new federal rescue aid package that will likely be enacted soon will spur growth and hiring in the coming months. Many analysts foresee the economy expanding at an annual rate of at least 5% in the current quarter and 7% for all of 2021.

Already, crucial sectors of the economy are showing signs of picking up as vaccinations increase, federal aid spreads through the economy and the Fed’s low-rate policies fuel borrowing and spending. Last month, America’s consumers bounced back from months of retrenchment to step up their spending by 2.4% — the sharpest increase in seven months and a sign that the economy may be poised to sustain a recovery.

The solid gain suggested that many people were growing more confident about spending, especially after receiving $600 checks that went to most adults early this year in a federal economic aid package. Additional relief is likely for American households and businesses as Congress considers Biden’s new aid package.

At the same time, rising bond yields in the financial markets are pointing to worries that higher inflation could be on the way as the economy recovers. This week, Lael Brainard, a member of the Fed’s Board of Governors, sought to calm investors by stressing that the Fed, while generally optimistic in its outlook, is still a long way off from raising interest rates or otherwise lessening its support for the economy.
