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.

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 destination for tourists and seasonal residents. So much of the population is seasonal such that the town’s population swells significantly during the vacation season, and drops again when the season ends. Because of this, much of the local economy is centered around tourism; some businesses may be operated only during the high season. During the low season, year-round residents will notice that the city is a substantially quieter place to live.

The town is relatively quiet, having a combination of lower population density and few of those groups of people who have a tendency to be noisy. For example, Arnold has relatively fewer families with younger children, and/or college students. Combined, this makes Arnold a pretty quiet place to live overall. If you like quiet, you will probably enjoy it here.
