ZIP 60102 vs ZIP 60118

This side-by-side compares ZIP 60102 (Algonquin, IL) and ZIP 60118 (Dundee, IL) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 60102 has a population of 32,193 at 860 people per square mile, while ZIP 60118 has 15,851 at 304 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 60102 reports a median household income of $132,949 against $106,912 in ZIP 60118, with per-capita income of $53,935 vs $61,249. The share of adults holding a bachelor's degree or higher is 42.5% in 60102 and 46.6% in 60118. Poverty rate reads 4.0% vs 5.2%, and unemployment 4.3% vs 3.5% — 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 $349,900 in 60102 versus $357,900 in 60118, with median rent of $1,735 and $1,587 per month respectively. Homeownership rate is 88.3% vs 67.7%. 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.
