U.S. manufacturing output unexpectedly fell in January and recorded its biggest drop since 2009 as cold weather disrupted production, the latest indication the economy got off to weak start this year.
Factory production fell 0.8 percent last month, the largest decline since May 2009, the Federal Reserve said on Friday. Output had increased 0.3 percent in December.
The Fed attributed the first decline in factory output to "severe weather that curtailed production in some parts of the country."
Manufacturing joined retail sales and employment in suggesting a step-back in growth early in the first quarter as cold weather takes its toll.
