Earlier this month, the Atlanta Regional Commission released updated county-by-county population updates, including Cobb County surpassing the 750,000 mark.
That’s a growth of more than 12,800 new residents in Cobb County in the last year, and up from 727,521 at the mid-decade U.S. Census update in 2015.
It was during that update two years ago that the ZIP codes making up East Cobb essentially passed 200,000 for the first time. This area, which spreads a little beyond the understood place-name identity of East Cobb (especially west of Interstate 75), includes 26 percent of the current Cobb population.
ZIP code 30062, located in the heart of East Cobb, has more people than Marietta, Cobb’s largest city.
If the East Cobb-area ZIP codes were incorporated, their present population of 205,763 would constitute the second-largest city in the metro region behind the city of Atlanta. (The subject of East Cobb cityhood has come up occasionally over the years, most recently when former Cobb Commission chairman Bill Byrne was vying for his old job in 2012. His “City of East Cobb” proposal went nowhere.)
The ARC calculations didn’t get granular below the county level, but we wanted to dig a little deeper and found the following breakdown of East Cobb-area ZIP codes at Georgia Demographics:
- ZIP Code 30062: Population 65,206; Whites 69.5%, Blacks 13.3%, Hispanics 8.4%; Median household income $88,063; Average age 39.9 years old;
- ZIP Code 30066: Population 52,930; Whites 73%, Blacks 10.2%, Hispanics 8,2%; Median household income $80,766; Average age 41 years old;
- ZIP Code 30067: Population 47,556; Whites 49%, Blacks 31.1%, Hispanics 10.2%; Median household income $51,088; Average age 33.1 years old;
- ZIP Code 30068: Population 32,068; Whites 76.6%, Asians 8%, Blacks 6.2%; Median household income $98,786; Average age 44.1 years old.
The Roswell ZIP Code 30075 includes the extreme northeast portion of Cobb County, or about 8,003 residents of the 54,858 population of the ZIP Code. The Georgia Demographics data didn’t make any county splits, but 30075 overall breaks down as follows: Whites 74.4%, Blacks 11.4%, Hispanics 7.2%; Median income $102,258; Average age 42.3 years old.
The useful City-Data.com site has even more demographic breakdowns by ZIP code, including median home cost, education levels, tax, pension and charity information, and more.
For 2040, the ARC is projecting Cobb’s population to be at 885,062, an increase of 157,541 people since the 2015 Census update.
