What it’s like
The place. Altadena is a community in Los Angeles County where most homes are lived in by their owners, and where residents are older than the typical age across much of the country. Incomes run well above the county's, and a good share of adults hold a four-year degree. Homes and rents are on the expensive side, and a fair number of residents work from home.
Work. Residents work mainly in schools, hospitals and social care, with many others in professional and business services, banks, insurance and property, and media and telecoms. Workplaces in Altadena itself include the Aveson School of Leaders District, Catalina Island Camps and Tom Sawyer Camps. The typical commute is a fairly long one, and unemployment in the county has eased compared with a year earlier.
Things to do. The Norton Simon Museum, a museum, and The Huntington Library, Art Museum, and Botanical Gardens, a botanical garden, are both a short drive away. Farther afield, a longer drive reaches the Hollywood Sign, a tourist attraction, and Disneyland, an amusement park. Winters are mild, summers are hot, and there is little or no snow, with rain that is on the modest side.

Natural hazards
- WildfireVery high
- EarthquakesRelatively high
- Inland floodingRelatively high
- AvalanchesRelatively moderate
FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Altadena’s census tracts, against the rest of the country; all of them together, relatively high. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.
From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on Los Angeles County and the Los Angeles-Long Beach-Anaheim, CA metro.
