ZIP 83402 vs ZIP 83404

This side-by-side compares ZIP 83402 (Idaho Falls, ID) and ZIP 83404 (Idaho Falls, ID) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 83402 has a population of 26,069 at 66 people per square mile, while ZIP 83404 has 21,606 at 312 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 83402 reports a median household income of $74,517 against $82,103 in ZIP 83404, with per-capita income of $34,426 vs $39,871. The share of adults holding a bachelor's degree or higher is 32.1% in 83402 and 37.1% in 83404. Poverty rate reads 12.8% vs 8.3%, and unemployment 2.5% vs 5.0% — 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 $334,900 in 83402 versus $394,300 in 83404, with median rent of $989 and $1,070 per month respectively. Homeownership rate is 63.9% 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.
