ZIP 18020 vs ZIP 18017

This side-by-side compares ZIP 18020 (Bethlehem, PA) and ZIP 18017 (Bethlehem, PA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 18020 has a population of 20,447 at 571 people per square mile, while ZIP 18017 has 37,549 at 897 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 18020 reports a median household income of $126,166 against $91,173 in ZIP 18017, with per-capita income of $56,266 vs $46,344. The share of adults holding a bachelor's degree or higher is 42.7% in 18020 and 40.9% in 18017. Poverty rate reads 5.0% vs 10.5%, and unemployment 3.0% vs 5.3% — 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 $370,200 in 18020 versus $336,100 in 18017, with median rent of $1,534 and $1,597 per month respectively. Homeownership rate is 85.8% vs 67.0%. 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.
