ZIP 87942 has a population of 898 at 2 people per square mile, while ZIP 87931 has 634 at 2 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 87942 reports a median household income of $42,308 against in ZIP 87931, with per-capita income of $28,729 vs $31,879.

Poverty rate reads 4.3% vs 22.2%, and unemployment 19.6% vs 0.0% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

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.
