(WASHINGTON) — The number of Americans applying for unemployment benefits rose last week to the highest level since mid-November, but still low by historic standards. U.S. jobless claims climbed by 23,000 last week to 230,000, the Department of Labor said Thursday. The four-week moving average, which smooths out week-to-week blips, rose nearly 6,300 to almost 211,000. The weekly applications, a proxy for layoffs, have risen in four of the last five weeks, a period that runs in tandem with the spread of the omicron variant.
