Arnold is a medium-sized coastal town (i.e. on the ocean, a bay, or inlet) located in the state of Maryland. With a population of 24,064 people and six associated neighborhoods, Arnold is the 49th largest community in Maryland.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 21.16% 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.

Finally, Arnold’s overall crime rate is lower than average for the country.
