Greensboro, GA — Siloam, GA

This side-by-side compares ZIP 30642 (Greensboro, GA) and ZIP 30665 (Siloam, GA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 30642 has a population of 11,001 at 22 people per square mile, while ZIP 30665 has 80 at 13 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 30642 reports a median household income of $95,527 against in ZIP 30665, with per-capita income of $68,902 vs $32,056. The share of adults holding a bachelor's degree or higher is 44.1% in 30642 and 18.0% in 30665. Poverty rate reads 9.9% vs 23.1%, and unemployment 4.0% vs 0.0% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Homeownership rate is 79.7% vs 70.2%. 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.
