Source:

Millersville, MD — Crownsville, MD

This side-by-side compares ZIP 21108 (Millersville, MD) and ZIP 21032 (Crownsville, MD) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 21108 has a population of 17,964 at 531 people per square mile, while ZIP 21032 has 8,848 at 194 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 21108 reports a median household income of $151,324 against $168,653 in ZIP 21032, with per-capita income of $64,218 vs $79,334. The share of adults holding a bachelor's degree or higher is 55.3% in 21108 and 51.2% in 21032. Poverty rate reads 3.5% vs 2.2%, and unemployment 3.3% vs 2.8% — 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 $555,000 in 21108 versus $682,100 in 21032, with median rent of $2,049 and $2,508 per month respectively. Homeownership rate is 88.5% vs 89.5%. 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.
