ZIP 20837 vs ZIP 20165

This side-by-side compares ZIP 20837 (Poolesville, MD) and ZIP 20165 (Sterling, VA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 20837 has a population of 5,789 at 53 people per square mile, while ZIP 20165 has 32,383 at 1,273 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 20837 reports a median household income of $174,063 against $183,076 in ZIP 20165, with per-capita income of $71,211 vs $74,859. The share of adults holding a bachelor's degree or higher is 57.1% in 20837 and 67.4% in 20165. Poverty rate reads 8.7% vs 3.1%, and unemployment 3.5% vs 4.0% — 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 $772,300 in 20837 versus $704,800 in 20165, with median rent of $1,996 and $2,531 per month respectively. Homeownership rate is 91.9% vs 77.6%. 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.
