The Labor Department’s January survey will include revisions making data for previous months look stronger in some cases and weaker in others.

The January jobs report revealed fewer new jobs than expected but the unemployment ticked down slightly.

The unemployment rate, which is derived from a separate survey, declined to 4% from 4.1% the prior month. Economists expected the unemployment rate to remain unchanged. Average hourly earnings increased 0.5% in January, which was higher than forecast.

U.S. job growth likely slowed in January, partly restrained by wild fires in California and cold weather across much of the country.
