ZIP 21131 vs ZIP 21111

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.
