ZIP 75166 vs ZIP 75087

This side-by-side compares ZIP 75166 (Lavon, TX) and ZIP 75087 (Rockwall, TX) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 75166 has a population of 3,070 at 90 people per square mile, while ZIP 75087 has 28,145 at 415 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 75166 reports a median household income of $132,101 against $129,484 in ZIP 75087, with per-capita income of $53,730 vs $53,291. The share of adults holding a bachelor's degree or higher is 40.9% in 75166 and 49.3% in 75087. Poverty rate reads 1.5% vs 3.8%, and unemployment 3.5% vs 3.7% — 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 $396,600 in 75166 versus $435,400 in 75087, with median rent of $2,203 and $1,758 per month respectively. Homeownership rate is 90.9% vs 81.2%. 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.
