East Cobb is not a city or a Census-defined place, so the Census Bureau publishes no “East Cobb” population. The closest measure is its four ZIP codes, 30062, 30066, 30067 and 30068, which the bureau counts as ZIP code tabulation areas. Together they had 211,829 residents in the 2020 census, up 19,980, or 10.4%, from 191,849 in 2010, according to the 2020 census and the 2010 census. That was about 28% of Cobb County’s 766,149 people.
The bureau’s newer 2020-2024 American Community Survey estimates 205,198 people in the four ZIP codes. That figure is a five-year survey average with a margin of error of about 2,000 to 3,100 people per ZIP code, so it cannot be read as a drop from the 2020 count.

How to read these figures
- Census counts (2010, 2020) are full counts as of April 1 of those years.
- The American Community Survey samples households over five years; each figure has a margin of error, larger for small areas.
- ZIP codes are not neighborhoods. ZIP code areas are drawn for mail delivery, not to match East Cobb as residents describe it, so these totals are an approximation.
