The U.S. created just 38,000 new jobs in May and hiring in the prior two months was weaker than originally reported, casting doubt on whether the Federal Reserve will raise interest rates later in June. The number of new jobs was the smallest the economy has created since the fall of 2010. Economists polled by MarketWatch had predicted an increase of 155,000 nonfarm jobs. The unemployment rate, in a surprising twist, fell to 4.7% from 5% to mark the lowest level since the month before the Great Recession began in December 2007. Yet the decline owed almost entirely to 458,000 people leaving the labor force.
