WASHINGTON (AP) — The number of Americans applying for unemployment benefits rose by 61,000 last week to 719,000, signaling that many employers are still cutting jobs even as more businesses reopen, vaccines are increasingly administered and federal aid spreads through the economy. The Labor Department said Thursday that the number of claims increased from 658,000 the week before. Though the pace of applications has dropped sharply since early this year, they remain high by historical standards: Before the pandemic flattened the economy a year ago, jobless claims typically ran below 220,000 a week. Still, the four-week average of claims, which smooths out week-to-week gyrations, fell by 10,500 to 719,000 — the fewest since mid-March 2020, just before the pandemic began to cause widespread layoffs.
