ZIP 31407 vs ZIP 31408

This side-by-side compares ZIP 31407 (Port Wentworth, GA) and ZIP 31408 (Savannah, GA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 31407 has a population of 7,244 at 97 people per square mile, while ZIP 31408 has 9,952 at 157 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 31407 reports a median household income of $81,124 against $45,839 in ZIP 31408, with per-capita income of $37,418 vs $21,932. The share of adults holding a bachelor's degree or higher is 36.6% in 31407 and 11.1% in 31408. Poverty rate reads 8.7% vs 12.1%, and unemployment 6.3% vs 9.8% — 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 $256,300 in 31407 versus $169,700 in 31408, with median rent of $1,830 and $1,252 per month respectively. Homeownership rate is 48.5% vs 44.7%. 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.
