ZIP 83406 vs ZIP 83401

This side-by-side compares ZIP 83406 (Idaho Falls, ID) and ZIP 83401 (Idaho Falls, ID) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 83406 has a population of 15,902 at 61 people per square mile, while ZIP 83401 has 37,966 at 94 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 83406 reports a median household income of $86,991 against $78,497 in ZIP 83401, with per-capita income of $36,956 vs $34,222. The share of adults holding a bachelor's degree or higher is 39.8% in 83406 and 28.9% in 83401. Poverty rate reads 5.6% vs 10.5%, and unemployment 5.4% vs 5.4% — 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 $392,200 in 83406 versus $358,700 in 83401, with median rent of $1,367 and $1,176 per month respectively. Homeownership rate is 69.5% vs 75.3%. 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.
