ZIP 19975 vs ZIP 21813

This side-by-side compares ZIP 19975 (Selbyville, DE) and ZIP 21813 (Bishopville, MD) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 19975 has a population of 8,253 at 117 people per square mile, while ZIP 21813 has 2,852 at 44 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 19975 reports a median household income of $88,568 against $121,472 in ZIP 21813, with per-capita income of $60,340 vs $70,018.

Poverty rate reads 4.4% vs 4.1%, and unemployment 5.5% vs 3.3% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Homeownership rate is 88.2% vs 80.6%. 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.
