About Alameda County, California

Alameda scores near the national median

With a composite score of 49.2, Alameda County sits just below the national median of 50.0, placing it at the 48th percentile nationwide. This puts the county right in the middle of the livability spectrum across America, neither a clear winner nor a struggling community. The score reflects a county in transition, with distinct strengths and challenges offsetting each other.

Below average for California overall

Alameda's 49.2 score falls notably short of California's 61.3 state average, ranking it in the lower half of the state's 58 counties. Among its Bay Area peers, Alameda faces more housing affordability pressure than many comparable regions. This gap reflects the county's struggle with cost-of-living challenges despite strong income levels.

Tax relief and strong household earnings

Alameda excels with an exceptionally low tax burden—a score of 80.8 reflects an effective tax rate of just 0.762%. The county's median household income of $126,240 ranks among California's highest, giving residents strong purchasing power relative to most Americans. These financial advantages make Alameda attractive for professionals and established families seeking tax efficiency.

Housing costs strain affordability

With a cost score of just 21.3, Alameda faces a critical affordability crisis: the median home value of $1,057,400 and monthly rent at $2,318 are among California's highest. This means high-earning households still struggle with housing as a percentage of income, limiting opportunity for middle-income families. Data on safety, health, schools, and water quality remain unavailable but will provide important context for livability decisions.

For affluent professionals seeking tax savings

Alameda County suits high-income earners and established professionals who can absorb housing costs and prioritize tax efficiency over affordability. The county's strong incomes and low tax rate create a niche appeal for dual-income households and business owners. However, those seeking affordable housing or middle-income stability should explore alternatives in less expensive California regions.

The Bay Area affordability spectrum

With a composite risk score of 99.78, Alameda County faces very high natural disaster risk—well above the national average. The county's rating places it among the most hazard-exposed areas in the United States, driven by earthquake, flood, and wildfire threats.

Among California's riskiest counties

Alameda's composite score of 99.78 exceeds California's state average of 88.72, ranking the county in the upper tier of risk across the state. This elevated exposure reflects the Bay Area's geological volatility and urban density in flood-prone areas.
