The US economy added 151,000 jobs in January, helping to push the country’s unemployment rate down to 4.9%. The number was lower than expected and is a sharp slowdown from December, when 292,000 jobs were added. Job losses in transport and education weighed on the numbers, the Bureau of Labor Statistics said. Last week, figures showed that US economic growth slowed to an annual rate 0.7% in the final three months of 2015, from 2% in the previous quarter. Trading on Wall Street suggests investors are concerned that the slowdown in job creation could be a further sign of a weakening US economy. But some analysts focused on the positive – that weaker job numbers meant another rise in interest rates was unlikely for now.
