ZIP 21111 vs ZIP 21131

This side-by-side compares ZIP 21111 (Monkton, MD) and ZIP 21131 (Phoenix, MD) using the same Census ACS 5-Year table fields for both, no averages swapped in, no national proxies. ZIP 21111 has a population of 4,903 at 54 people per square mile, while ZIP 21131 has 7,253 at 126 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 21111 reports a median household income of $136,304 against $197,619 in ZIP 21131, with per-capita income of $69,759 vs $82,991. The share of adults holding a bachelor's degree or higher is 63.7% in 21111 and 73.9% in 21131. Poverty rate reads 6.3% vs 4.7%, and unemployment 8.6% vs 3.9% - 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 $607,200 in 21111 versus $686,000 in 21131, with median rent of $1,359 and - per month respectively. Homeownership rate is 95.5% vs 98.4%. 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.
