ZIP 98010 vs ZIP 98051

This side-by-side compares ZIP 98010 (Black Diamond, WA) and ZIP 98051 (Ravensdale, WA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 98010 has a population of 5,025 at 129 people per square mile, while ZIP 98051 has 3,270 at 25 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 98010 reports a median household income of $142,048 against $136,439 in ZIP 98051, with per-capita income of $66,955 vs $57,783. The share of adults holding a bachelor's degree or higher is 52.7% in 98010 and 33.0% in 98051. Poverty rate reads 2.3% vs 1.3%, and unemployment 1.2% vs 2.1% — 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 $775,400 in 98010 versus $790,500 in 98051, with median rent of $1,657 and $1,727 per month respectively. Homeownership rate is 85.7% vs 92.9%. 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.
