Annapolis, MD — Annapolis, MD

This side-by-side compares ZIP 21402 (Annapolis, MD) and ZIP 21409 (Annapolis, MD) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies.

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 21402 reports a median household income of $80,893 against $147,151 in ZIP 21409, with per-capita income of $31,226 vs $69,763.

Poverty rate reads 1.2% vs 3.4%, and unemployment 1.0% vs 3.2% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Homeownership rate is 0.0% vs 91.0%. 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.
