WASHINGTON — The number of newly laid-off workers seeking unemployment benefits fell more than expected last week, the second straight drop from a six-year high, according to government data released Thursday.

The Labor Department reported that applications for jobless benefits dropped to 432,000, down by 13,000 from the previous week. It was a bigger improvement than analysts expected.

But claims remain elevated compared with recent years. The four-week average climbed to 445,750, the highest level in almost seven years.

Unemployment claims have increased in the past several weeks, partly reflecting an outreach effort by the Labor Department to notify people of a 13-week benefit extension approved by Congress in June. The action has turned up some people eligible to file new claims, according to the department.

That effort — coupled with businesses cutting jobs due to higher energy costs, tighter credit markets and a slowing economy — caused claims to spike to a six-year high of 457,000 for the week of Aug. 2, the largest total since claims surged to 479,000 in March 2002.

The increase more than six years ago occurred the last time Congress extended benefits to deal with the impact of soaring layoffs due to a weak economy.
