Housing costs in Arnold 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.

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.

Of important note, Arnold is also a town of artists. Arnold has more artists, designers and people working in media than 90% of the communities in America. This concentration of artists helps shape Arnold’s character.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 26.51% 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.

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.

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.

Compared to the rest of the country, citizens of Arnold spend much less time in their cars: on average, their commute to work is only 15.45 minutes. This also means that noise and pollution levels in the town are less than they would otherwise be.

As is often the case in a small town, Arnold doesn't have a public transportation system that people use for their commute.

The education level of Arnold ranks among the highest in the nation. Of the 25-and-older adult population in Arnold, 41.16% have at least a bachelor's degree. The typical US community has just 21.84% of its adults holding a bachelor's degree or graduate degree.
