Source:
White Castle, LA – Donaldsonville, LA
This side-by-side compares ZIP 70788 (White Castle, LA) and ZIP 70346 (Donaldsonville, LA) using the same Census ACS 5-Year table fields for both, no averages swapped in, no national proxies. ZIP 70788 has a population of 4,051 at 15 people per square mile, while ZIP 70346 has 10,925 at 82 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 70788 reports a median household income of $33,079 against $35,280 in ZIP 70346, with per-capita income of $21,433 vs $22,826. The share of adults holding a bachelor's degree or higher is 12.1% in 70788 and 11.6% in 70346. Poverty rate reads 37.8% vs 35.3%, and unemployment 12.9% vs 11.2% - these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Homeownership rate is 53.0% vs 55.4%. 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.
