Ninilchik, AK — Clam Gulch, AK

This side-by-side compares ZIP 99639 (Ninilchik, AK) and ZIP 99568 (Clam Gulch, AK) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 99639 has a population of 1,131 at 2 people per square mile, while ZIP 99568 has 279 at 6 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 99639 reports a median household income of $47,333 against $85,000 in ZIP 99568, with per-capita income of $33,502 vs $53,095.

Poverty rate reads 19.7% vs 17.8%, and unemployment 5.5% vs 7.3% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Homeownership rate is 85.3% vs 95.2%. 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.
