The number of Americans filing applications for unemployment benefits rose more than expected last week, but there is still no sign of a significant pickup in layoffs even as economic growth has shifted into lower gear.

Initial claims for state unemployment benefits increased 10,000 to a seasonally adjusted 227,000 for the week ended June 22, the Labor Department said on Thursday. Data for the prior week was revised to show 1,000 more applications received than previously reported.

Economists polled by Reuters had forecast claims rising to 220,000 in the latest week. The Labor Department said claims for California and Mississippi were estimated.

Claims could rise further in the coming weeks as auto manufacturers temporarily shut down assembly plants for summer retooling. Companies implement the plant closures at different times, which can throw off the model the government uses to remove seasonal fluctuations from the data.
