ZIP 85140 vs ZIP 85143

This side-by-side compares ZIP 85140 (San Tan Valley, AZ) and ZIP 85143 (San Tan Valley, AZ) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 85140 has a population of 36,711 at 423 people per square mile, while ZIP 85143 has 35,015 at 376 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 85140 reports a median household income of $101,477 against $93,707 in ZIP 85143, with per-capita income of $41,200 vs $35,206. The share of adults holding a bachelor's degree or higher is 30.1% in 85140 and 22.2% in 85143. Poverty rate reads 7.5% vs 8.2%, and unemployment 4.4% vs 3.9% — 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 $445,000 in 85140 versus $389,200 in 85143, with median rent of $2,062 and $2,074 per month respectively. Homeownership rate is 85.8% vs 80.1%. 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.
