DeKalb County is included in the Atlanta–Sandy Springs–Alpharetta, GA Metropolitan Statistical Area. It contains roughly 10% of the city of Atlanta (the other 90% lies in Fulton County). Stonecrest is the largest city that is entirely within the county. DeKalb is primarily a suburban county.
In 2009, DeKalb earned the Atlanta Regional Commission's "Green Communities" designation for its efforts in conserving energy, water and fuel, investing in renewable energy, reducing waste, and protecting and restoring natural resources.
In 2021, the non-profit American Rivers named DeKalb's South River the fourth-most endangered river in the United States, citing "the egregious threat that ongoing sewage pollution poses to clean water and public health."
In recent years, some communities in North DeKalb have incorporated, following a trend in other suburban areas around Metro Atlanta. Stonecrest, Dunwoody and Brookhaven are now the largest cities that are entirely contained within the county.
