ZIP 94565 vs ZIP 94521

This side-by-side compares ZIP 94565 (Pittsburg, CA) and ZIP 94521 (Concord, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94565 has a population of 84,641 at 1,088 people per square mile, while ZIP 94521 has 41,249 at 1,228 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 94565 reports a median household income of $95,556 against $125,899 in ZIP 94521, with per-capita income of $36,361 vs $59,781. The share of adults holding a bachelor's degree or higher is 21.3% in 94565 and 44.6% in 94521. Poverty rate reads 12.0% vs 5.2%, and unemployment 8.2% vs 6.1% — 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 $583,800 in 94565 versus $853,200 in 94521, with median rent of $2,210 and $2,404 per month respectively. Homeownership rate is 60.9% vs 74.3%. 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.
