ZIP 84003 vs ZIP 84004

This side-by-side compares ZIP 84003 (American Fork, UT) and ZIP 84004 (Alpine, UT) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 84003 has a population of 42,384 at 283 people per square mile, while ZIP 84004 has 9,818 at 129 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 84003 reports a median household income of $120,330 against $170,500 in ZIP 84004, with per-capita income of $47,360 vs $68,053. The share of adults holding a bachelor's degree or higher is 49.9% in 84003 and 54.6% in 84004. Poverty rate reads 5.4% vs 7.4%, and unemployment 3.4% vs 1.9% — 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 $630,300 in 84003 versus $980,300 in 84004, with median rent of $1,721 and $3,501 per month respectively. Homeownership rate is 73.7% vs 88.8%. 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.
