ZIP 30078 vs ZIP 30039

This side-by-side compares ZIP 30078 (Snellville, GA) and ZIP 30039 (Snellville, GA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 30078 has a population of 33,057 at 753 people per square mile, while ZIP 30039 has 41,517 at 640 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 30078 reports a median household income of $98,257 against $93,701 in ZIP 30039, with per-capita income of $39,107 vs $33,617. The share of adults holding a bachelor's degree or higher is 40.6% in 30078 and 36.2% in 30039. Poverty rate reads 9.3% vs 9.8%, and unemployment 4.8% vs 5.6% — 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 $353,200 in 30078 versus $319,700 in 30039, with median rent of $1,788 and $2,059 per month respectively. Homeownership rate is 82.6% vs 79.4%. 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.
