ZIP 30039 vs ZIP 30078

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