DeKalb County was created in 1822 from Henry, Gwinnett and Fayette counties. It was named for Baron Johann de Kalb, a German soldier who fought for the Continental Army in the American Revolutionary War. The oldest existing house in the county is the 1831 Goodwin House, located along Peachtree Road in Brookhaven. Dekalb is located six miles east of downtown, plus home of Georgia’s #1 tourism attraction, Stone Mountain Park. The population of the county is approximately 700,000. DeKalb County’s county seat is the City of Decatur and it is the third-most-populated county in Metro Atlanta. Until the 1960s, DeKalb was a mainly agricultural county, but as the sprawl of the metropolitan Atlanta region expanded, the County became increasingly urbanized. It is primarily a suburban county, and is the second-most-affluent county with an African-American majority in the United States, behind Prince George’s County, Maryland, in suburban Washington D.C. DeKalb is the most ethnically diverse county in the Southeast with over 64 spoken languages representing Asian, Hispanic, European, and African cultures, to name a few.
