Initial claims for state unemployment benefits decreased 9,000 to a seasonally adjusted 221,000 for the week ended Feb. 3, the Labor Department said on Thursday. Claims fell to 216,000 in mid-January, which was the lowest level since January 1973.

Economists polled by Reuters had forecast claims rising to 232,000 in the latest week. Last week marked the 153rd straight week that claims remained below the 300,000 threshold, which is associated with a strong labor market. That is the longest such stretch since 1970, when the labor market was much smaller.

The labor market is near full employment, with the jobless rate at a 17-year low of 4.1 percent. The tighter labor market is starting to exert upward pressure on wage growth.
