The US added fewer jobs than expected in December amid a decline in retail employment, but a pick-up in monthly wage gains pointed to labour market strength that could pave the way for the Federal Reserve to increase interest rates in March.

Nonfarm payrolls increased by 148,000 jobs last month after surging by 252,000 in November, the Labour Department said on Friday. Retail payrolls decreased by 20,300 in December, the largest drop since March, despite reports of a strong holiday shopping season.

The unemployment rate was unchanged at a 17-year low of 4.1 percent. Economists polled by Reuters had forecast payrolls rising by 190,000 in December. The economy needs to create 75,000 to 100,000 jobs per month to keep up with growth in the working-age population.

"We do not think that today's employment report will keep the Federal Reserve from tightening again at the March policy meeting, given other strong recent economic data," said David Berson, chief economist at Nationwide in Columbus, Ohio.

Job growth surged in October and November after being held back in September by back-to-back hurricanes, which destroyed infrastructure and homes and temporarily dislocated some workers in Texas and Florida.

Taking some sting out of the moderation in job gains, average hourly earnings rose 9 cents, or 0.3 percent, in December after gaining 0.1 percent in the prior month. That lifted the annual increase in wages to 2.5 percent from 2.4 percent in November.
