Arnold is a very small town located in the state of California. With a population of 3,288 people and four associated neighborhoods, Arnold is the 593rd largest community in California.

And if you like science, one thing you'll find is that Arnold has lots of scientists living in town - whether they be life scientists, physical scientists (like astronomers), or social scientists (like geographers!). So, if you're scientific-minded, you might like it here too.

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

Telecommuters are a relatively large percentage of the workforce: 42.12% of people work from home. While this number may seem small overall, as a fraction of the total workforce it is high relative to the nation. 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.

Another notable thing is that Arnold is an extremely popular vacation destination. A significant portion of the population is seasonal. During the vacation season, the town experiences a large influx of people who take up residence in second homes they own in the area. As the vacation season ends, the population drops again, leaving behind a substantially quieter and smaller town.

Residents will find that the town is relatively quiet. This is because it is not over-populated, and it has fewer college students, renters, and young children - all of whom can be noisy at times. So, if you're looking for a relatively peaceful place to live, Arnold is worth considering.
