ZIP 15551 vs ZIP 15557

This side-by-side compares ZIP 15551 (Markleton, PA) and ZIP 15557 (Rockwood, PA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 15551 has a population of 860 at 9 people per square mile, while ZIP 15557 has 3,684 at 16 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 15551 reports a median household income of $67,727 against $61,042 in ZIP 15557, with per-capita income of $31,929 vs $32,256. The share of adults holding a bachelor's degree or higher is 11.5% in 15551 and 17.9% in 15557. Poverty rate reads 3.1% vs 10.2%, and unemployment 3.9% vs 6.7% — 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 $160,600 in 15551 versus $135,500 in 15557, with median rent of $742 and $719 per month respectively. Homeownership rate is 86.1% vs 83.8%. 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.
