U.S. employers hired more workers than expected in March, a move spurred by increased vaccinations and more pandemic relief money from the government, cementing expectations that an economic boom was underway.

The Labor Department announced on Friday that nonfarm payrolls rose by 916,000 jobs last month. That was the biggest gain since last August. Data for February was revised higher to show 468,000 jobs created instead of the previously reported 379,000.

Economists polled by Reuters had forecast payrolls jumping by 647,000 jobs in March. The unemployment rate dropped to 6.0% last month from 6.2% in February. The unemployment rate has been understated by people misclassifying themselves as being “employed but absent from work.”

The closely watched employment report marked a painful anniversary for the labor market. The March 2020 employment report was the first to reflect the compulsory shutdowns of non-essential businesses such as gyms, bars and restaurants to slow the onset of the just-emerging coronavirus pandemic.

Around 1.7 million jobs were lost that month, and another 20.7 million would disappear in April. Economists estimate it could take at least 2 years to recoup the more than 22 million jobs lost during the COVID-19 pandemic.

As of Tuesday morning, the U.S. had administered 147.6 million shots of COVID-19 vaccines in the country and distributed 189.5 million doses, according to the U.S. Centers for Disease Control and Prevention. The White House’s massive $1.9 trillion pandemic relief package approved in March is sending additional $1,400 checks to qualified households and fresh funding for businesses.

Economists expect job growth will average at least 700,000 per month in the 2nd and 3rd quarters. That, combined with the fiscal stimulus and about $19 trillion in excess savings accumulated by households during the pandemic, is expected to unleash a powerful wave of pent-up demand.

First-quarter gross domestic product estimates are as high as a 10.0% annualized rate. The economy grew at a 4.3% pace in the 4th quarter. Growth this year could top 7%, which would be the fastest since 1984. The economy contracted 3.5% in 2020, the worst performance in 74 years.
