ZIP 85051 vs ZIP 85021

This side-by-side compares ZIP 85051 (Phoenix, AZ) and ZIP 85021 (Phoenix, AZ) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 85051 has a population of 40,375 at 2,468 people per square mile, while ZIP 85021 has 37,743 at 2,167 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 85051 reports a median household income of $69,189 against $59,768 in ZIP 85021, with per-capita income of $28,709 vs $38,713. The share of adults holding a bachelor's degree or higher is 19.3% in 85051 and 35.6% in 85021. Poverty rate reads 13.8% vs 17.4%, and unemployment 6.7% vs 8.0% — 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 $326,300 in 85051 versus $470,400 in 85021, with median rent of $1,322 and $1,313 per month respectively. Homeownership rate is 55.2% vs 39.4%. 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.
