That is down from 8.3 percent in September and 9.4 percent in October 2011.
The new numbers were announced early Thursday by the Georgia Department of Labor.
The rate declined because of an increase of 19,500 new jobs in metro Atlanta, officials said.
There were 2.35 million jobs in October, up from 2.33 million in September. During a one-year period, jobs were up in metro Atlanta by 33,700 — or 1.5 percent — from 2.32 million in October 2011, official said.
Among other metro areas, the Athens area continued to have the lowest jobless rate at 6.2 percent.
Metro Dalton had the highest unemployment rate of 11.3 percent.
