U.S. nonfarm payrolls grew by a seasonally adjusted 257,000 jobs in January, the Labor Department said today. Job creation was far stronger in prior months than previously estimated, with the government raising its estimates of new jobs in November and December by a combined 147,000, bringing November’s reading to 423,000 jobs added and making it the strongest month of private-sector hiring since 1997, according to the Wall Street Journal.
