ZIP 20640 vs ZIP 20658

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