WASHINGTON — The number of people seeking U.S. unemployment benefits plunged last week. But a big reason is that automakers have skipped some of their usual summer shutdowns to keep up with demand, causing fewer temporary auto layoffs.
Economists expect the number of Americans seeking unemployment aid to go back up in coming weeks.
The auto industry’s recovery has helped support the struggling U.S. economy. U.S. auto sales in the first half of the year jumped 15 percent over the same period a year ago. Sales of new vehicles surged in June. Automakers also began Independence Day promotions early, lifting sales at the end of the month.
The Labor Department adjusts the number of applications for unemployment aid to account for seasonal factors. But it didn’t anticipate fewer temporary shutdowns of auto plants this summer — and fewer auto layoffs. That distorted the seasonally adjusted data it released Thursday.
And that may largely explain why applications for unemployment aid tumbled 26,000 last week to a seasonally adjusted 350,000 — the fewest since March 2008.
Automakers traditionally close their plants in the first two weeks in July to prepare them to build new models, and their employees often file for unemployment benefits. But Ford Motor Co. said in May that it would reduce its usual two-week closing to just one week. And Chrysler canceled the normal two-week shutdowns at three factories.
Applications for unemployment benefits measure the pace of layoffs. When they consistently fall below 375,000, it generally suggests that hiring is strong enough to reduce the unemployment rate. The number has fluctuated at or above that level since April.
At the same time, hiring has slowed sharply compared with the first three months of the year. Employers added only 80,000 jobs in June, the third straight month of weak hiring. The unemployment rate was stuck at 8.2 percent.
