ZIP 18106 vs ZIP 18087

This side-by-side compares ZIP 18106 (Allentown, PA) and ZIP 18087 (Trexlertown, PA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 18106 has a population of 6,889 at 323 people per square mile, while ZIP 18087 has 738 at 263 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 18106 reports a median household income of $92,813 against $72,917 in ZIP 18087, with per-capita income of $50,875 vs $37,664. The share of adults holding a bachelor's degree or higher is 49.4% in 18106 and 42.7% in 18087. Poverty rate reads 6.6% vs 14.7%, and unemployment 8.4% vs 2.6% — 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 $412,200 in 18106 versus $346,100 in 18087, with median rent of $1,419 and $1,145 per month respectively. Homeownership rate is 82.5% vs 43.2%. 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.
