Cobb County is one of the most economically powerful counties in the Southeast. Home to Fortune 500 headquarters, the world's largest home improvement retailer, one of the nation's top defense contractors, and Georgia's largest integrated healthcare system, Cobb punches well above its weight for a county of 793,000 residents.

That education level is no accident. Cobb County has spent decades deliberately cultivating a business environment that attracts high-skill employers, and it shows. The county's median household income of $98,712 is well above both the state and national medians, and its unemployment rate of 3.1 percent as of September 2025 reflects a labor market that is consistently tighter than the metro average.
