ZIP 80108 vs ZIP 80134

This side-by-side compares ZIP 80108 (Castle Rock, CO) and ZIP 80134 (Parker, CO) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 80108 has a population of 22,612 at 246 people per square mile, while ZIP 80134 has 55,075 at 378 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 80108 reports a median household income of $181,049 against $146,778 in ZIP 80134, with per-capita income of $87,899 vs $64,461. The share of adults holding a bachelor's degree or higher is 65.5% in 80108 and 60.7% in 80134. Poverty rate reads 4.7% vs 3.2%, and unemployment 2.8% vs 2.5% — 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 $881,700 in 80108 versus $677,700 in 80134, with median rent of $2,044 and $2,118 per month respectively. Homeownership rate is 82.6% vs 79.7%. 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.
