ZIP 80128 vs ZIP 80123

This side-by-side compares ZIP 80128 (Littleton, CO) and ZIP 80123 (Littleton, CO) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 80128 has a population of 34,988 at 1,113 people per square mile, while ZIP 80123 has 44,795 at 1,458 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 80128 reports a median household income of $121,436 against $105,932 in ZIP 80123, with per-capita income of $58,152 vs $63,179. The share of adults holding a bachelor's degree or higher is 50.0% in 80128 and 53.7% in 80123. Poverty rate reads 4.9% vs 4.4%, and unemployment 3.6% vs 4.3% — 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 $586,000 in 80128 versus $620,100 in 80123, with median rent of $2,108 and $2,077 per month respectively. Homeownership rate is 84.3% vs 72.8%. 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.
