ZIP 21780 vs ZIP 21719

This side-by-side compares ZIP 21780 (Sabillasville, MD) and ZIP 21719 (Cascade, MD) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 21780 has a population of 1,625 at 28 people per square mile, while ZIP 21719 has 1,548 at 178 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 21780 reports a median household income of $83,785 against $65,809 in ZIP 21719, with per-capita income of $38,433 vs $43,121. The share of adults holding a bachelor's degree or higher is 24.7% in 21780 and 21.3% in 21719. Poverty rate reads 5.4% vs 4.3%, and unemployment 0.0% 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 $451,600 in 21780 versus $214,100 in 21719, with median rent of $1,374 and $1,460 per month respectively. Homeownership rate is 73.0% vs 85.6%. 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.
