Oceano is a somewhat small coastal town (i.e. on the ocean, a bay, or inlet) located in the state of California. With a population of 7,183 people and two associated neighborhoods, Oceano is the 467th largest community in California.

Housing costs in Oceano 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 Oceano has more people living here who work in computers and math than 95% of the places in the US.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 11.27% of the workforce. While this number may seem small overall, as a fraction of the total workforce this is high compared to the rest of the county. 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.

Oceano 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. Quite often, nautical areas such as these attract visitors and locals who come to enjoy the scenery and various waterfront activities.
