ZIP 94550 vs ZIP 94551

This side-by-side compares ZIP 94550 (Livermore, CA) and ZIP 94551 (Livermore, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 94550 has a population of 46,896 at 78 people per square mile, while ZIP 94551 has 36,867 at 181 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 94550 reports a median household income of $180,295 against $145,392 in ZIP 94551, with per-capita income of $82,802 vs $64,072. The share of adults holding a bachelor's degree or higher is 55.7% in 94550 and 48.1% in 94551. Poverty rate reads 4.8% vs 4.8%, and unemployment 3.0% vs 4.2% — 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 $1,202,500 in 94550 versus $978,500 in 94551, with median rent of $2,646 and $2,696 per month respectively. Homeownership rate is 73.5% vs 70.6%. 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.
