ZIP 19940 vs ZIP 21875

This side-by-side compares ZIP 19940 (Delmar, DE) and ZIP 21875 (Delmar, MD) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 19940 has a population of 5,574 at 52 people per square mile, while ZIP 21875 has 6,467 at 106 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 19940 reports a median household income of $65,024 against $83,665 in ZIP 21875, with per-capita income of $33,363 vs $39,076. The share of adults holding a bachelor's degree or higher is 19.9% in 19940 and 23.0% in 21875. Poverty rate reads 14.0% vs 6.2%, and unemployment 6.7% vs 2.7% — 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 $235,300 in 19940 versus $234,500 in 21875, with median rent of $1,037 and $1,559 per month respectively. Homeownership rate is 82.2% vs 68.5%. 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.
