Fewer Americans filed new claims for unemployment benefits last week, suggesting layoffs were subsiding.
Today's figures also strengthened expectations for another month of blockbuster job growth in April as a re-opening economy unleashes pent-up demand.
Initial claims for state unemployment benefits totalled a seasonally adjusted 547,000 for the week ended April 17 compared to 586,000 in the previous week.
Economists polled by Reuters had forecast 617,000 applications in the latest week.
It was the second week in a row that claims were below the 700,000 level since March 2020 when mandatory shutdowns of nonessential businesses like restaurants and bars were enforced to slow the first wave of Covid-19 infections.
Claims have remained high because of fraud, especially in California and Ohio.
The enhancement of the unemployment benefits programmes, including a weekly $300 subsidy, could also be encouraging some people to attempt to file a claim for assistance, though not every application is approved.
Latest Labor Department data on first payments show only a fraction of claims were successful over the past months.
The unprecedented surge in claims early in the pandemic could also be messing with the model that the government uses to strip seasonal fluctuations from the data.
Claims jumped to a record 6.149 million in early April 2020. In a healthy labour market, claims are normally in a 200,000 to 250,000 range.
The US has expanded vaccination eligibility to most American adults, and more than half that population has had at least one vaccine dose, according to the US Centers for Disease Control and Prevention.
A third of US adults are fully vaccinated, as well as 26% of the population overall, it said.
That, together with the White House's $1.9 trillion pandemic rescue package, has allowed for broader economic re-engagement.
The resulting surge in demand has left businesses scrambling for workers. US retail sales raced to a record high in March and factories are humming.
Last week's claims data covered the period during which the government surveyed business establishments for the nonfarm payrolls component of April's employment report. First-time filings have dropped from 765,000 in mid-March.
Claims are generally considered a leading labour market indicator, but they have lagged employment during the pandemic.
While the recent downward trend supports expectations for robust job gains in April, economists are keeping an eye on the number of people receiving benefits under both the regular state unemployment insurance and government-funded programmes to get a better read of the labour market's health.
The US economy created 916,000 jobs in March, the most in seven months. Still, employment remains 8.4 million jobs below its peak in February 2020.
