ZIP 21651 vs ZIP 21668

This side-by-side compares ZIP 21651 (Millington, MD) and ZIP 21668 (Sudlersville, MD) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 21651 has a population of 2,898 at 29 people per square mile, while ZIP 21668 has 1,904 at 15 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 21651 reports a median household income of $74,063 against $78,672 in ZIP 21668, with per-capita income of $32,745 vs $38,133. The share of adults holding a bachelor's degree or higher is 18.0% in 21651 and 18.2% in 21668. Poverty rate reads 8.3% vs 12.3%, and unemployment 3.3% vs 5.5% — 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 $326,800 in 21651 versus $348,400 in 21668, with median rent of $1,429 and $1,037 per month respectively. Homeownership rate is 77.8% vs 77.9%. 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.
