Source:

New Windsor, MD — Union Bridge, MD

This side-by-side compares ZIP 21776 (New Windsor, MD) and ZIP 21791 (Union Bridge, MD) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 21776 has a population of 5,735 at 63 people per square mile, while ZIP 21791 has 5,281 at 41 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 21776 reports a median household income of $133,409 against $93,015 in ZIP 21791, with per-capita income of $54,829 vs $41,286. The share of adults holding a bachelor's degree or higher is 38.0% in 21776 and 26.7% in 21791. Poverty rate reads 3.7% vs 5.1%, and unemployment 7.7% vs 2.0% — 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 $461,600 in 21776 versus $379,800 in 21791, with median rent of $1,297 and $1,457 per month respectively. Homeownership rate is 93.2% vs 81.7%. 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.
