The overall economy grew at an annual rate of 2 percent in the July-September quarter. That was up from 1.3 percent growth in the April-June period. Still, the growth is considered too slow to rapidly lower the unemployment rate.
Employers added 171,000 jobs in October and hiring was also stronger in August and September than first thought, the government said Friday. The unemployment rate rose to 7.9 percent from 7.8 percent in September. The increase mainly reflected the fact that many more people began looking for work last month and not all of them found jobs.
Service companies have been a key source of job growth this year. They have created about 90 percent of the net jobs added since January. Still, many of the new service jobs have been low-paying retail and restaurant positions.
The unemployment report was the last major snapshot of the economy before Tuesday's elections.
President Barack Obama will face voters with the highest unemployment rate of any incumbent since Franklin Roosevelt. Republican challenger Mitt Romney has made high unemployment and the weak economy the major point in his effort to deny Obama a second term.
The ISM reported last week that manufacturing expanded for a second month in October. The group's index showed manufacturing had contracted from June through August. Factories had struggled over the summer with weak consumer demand in the United States and slower global growth, which depressed export sales.
