Avalon is a very small coastal city (i.e. on the ocean, a bay, or inlet) located in the state of California. With a population of 3,267 people and two associated neighborhoods, Avalon is the 585th largest community in California. Avalon has a large stock of pre-World War II architecture, making it one of the older and more historic cities in the country.

Housing costs in Avalon are among some of the highest in the nation, although real estate prices here don't compare to real estate prices in the most expensive communities in California.

Also of interest is that Avalon has more people living here who work in computers and math than 95% of the places in the US.

A relatively large number of people in Avalon telecommute to their jobs. Overall, about 9.30% of the workforce works from home. While this may seem like a small number, as a fraction of the total workforce it ranks among the highest in the country. These workers are often telecommuters who work in knowledge-based, white-collar professions. For example, Silicon Valley has large numbers of people who telecommute. Other at-home workers may be self-employed people who operate small businesses out of their homes.

Avalon is also nautical, which means that parts of it are somewhat historic and touch the ocean or tidal bodies of water, such as inlets and bays. Such areas are often places that visitors and locals go for waterfront activities or taking in the scenery.
