ZIP 17566 vs ZIP 17536

This side-by-side compares ZIP 17566 (Quarryville, PA) and ZIP 17536 (Kirkwood, PA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 17566 has a population of 12,019 at 80 people per square mile, while ZIP 17536 has 2,839 at 51 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 17566 reports a median household income of $78,108 against $76,042 in ZIP 17536, with per-capita income of $36,339 vs $32,673. The share of adults holding a bachelor's degree or higher is 20.2% in 17566 and 16.9% in 17536. Poverty rate reads 7.9% vs 11.9%, and unemployment 3.1% vs 0.6% — 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 $306,200 in 17566 versus $339,200 in 17536, with median rent of $1,297 and $1,371 per month respectively. Homeownership rate is 72.5% vs 93.3%. 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.
