Akiachak, AK — Kwethluk, AK

This side-by-side compares ZIP 99551 (Akiachak, AK) and ZIP 99621 (Kwethluk, AK) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 99551 has a population of 627 at 133 people per square mile, while ZIP 99621 has 723 at 29 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 99551 reports a median household income of $30,000 against $51,917 in ZIP 99621, with per-capita income of $10,486 vs $14,175. The share of adults holding a bachelor's degree or higher is 6.8% in 99551 and 5.1% in 99621. Poverty rate reads 51.6% vs 30.9%, and unemployment 29.7% vs 29.1% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Homeownership rate is 69.8% vs 73.9%. 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.
