The September drop in U.S. unemployment benefited a broad number of demographic groups.
Unemployment rates fell for white, black and Hispanic workers, as well as teenagers, young adults and Americans ages 25 to 54.
The national unemployment rate declined to 7.2 percent last month, down from 7.3 percent in August and the lowest since November 2008. Still, unemployment remains elevated more than four years after the recession officially ended. And many subgroups of Americans are suffering even higher jobless rates.
