ZIP 61810 vs ZIP 61876

This side-by-side compares ZIP 61810 (Allerton, IL) and ZIP 61876 (Sidell, IL) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 61810 has a population of 361 at 7 people per square mile, while ZIP 61876 has 800 at 7 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 61810 reports a median household income of $90,625 against $60,956 in ZIP 61876, with per-capita income of $61,060 vs $31,726. The share of adults holding a bachelor's degree or higher is 22.3% in 61810 and 5.5% in 61876. Poverty rate reads 13.6% vs 12.3%, and unemployment 1.9% vs 2.4% — 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 $154,500 in 61810 versus $77,900 in 61876, with median rent of $763 and $675 per month respectively. Homeownership rate is 79.8% vs 94.2%. 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.
