ZIP 20658 vs ZIP 20640

This side-by-side compares ZIP 20658 (Marbury, MD) and ZIP 20640 (Indian Head, MD) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 20658 has a population of 854 at 110 people per square mile, while ZIP 20640 has 10,438 at 97 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 20658 reports a median household income of $104,375 against $100,593 in ZIP 20640, with per-capita income of $49,111 vs $49,439. The share of adults holding a bachelor's degree or higher is 31.7% in 20658 and 24.2% in 20640. Poverty rate reads 6.0% vs 8.3%, and unemployment 1.5% vs 3.9% — 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 $340,000 in 20658 versus $324,600 in 20640, with median rent of $1,609 and $1,529 per month respectively. Homeownership rate is 86.3% vs 78.7%. 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.
