ZIP 30040 vs ZIP 30028

This side-by-side compares ZIP 30040 (Cumming, GA) and ZIP 30028 (Cumming, GA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 30040 has a population of 54,653 at 359 people per square mile, while ZIP 30028 has 22,182 at 167 per square mile. That difference in population size and density alone reshapes how every other metric should be interpreted — a higher-income ZIP with 1,200 residents behaves very differently from one with 45,000.

On income and education, ZIP 30040 reports a median household income of $137,211 against $138,011 in ZIP 30028, with per-capita income of $55,882 vs $49,309. The share of adults holding a bachelor's degree or higher is 56.0% in 30040 and 44.6% in 30028. Poverty rate reads 5.0% vs 3.8%, and unemployment 3.4% vs 5.0% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Housing separates these two ZIPs further: median home value sits at $526,100 in 30040 versus $470,800 in 30028, with median rent of $2,075 and $2,270 per month respectively. Homeownership rate is 84.1% vs 86.7%. When reading the comparison table below, focus on paired metrics rather than single winners — a ZIP with lower home values and lower income is not strictly "worse" if rent-to-income ratios and commute times land in the same zone. Every value is pulled from the exact same ACS table so the two columns are genuinely comparable.
