Living in Arnold



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.

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 Maryland.

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.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 19.37% 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.

Because of many things, Arnold is a very good place for families to consider. With an enviable combination of good schools, low crime, college-educated neighbors who tend to support education because of their own experiences, and a high rate of home ownership in predominantly single-family properties, Arnold really has some of the features that families look for when choosing a good community to raise children. Is Arnold perfect? Of course not, and if you like frenetic nightlife, it will be far from your cup of tea. But overall this is a solid community, with many things to recommend it as a family-friendly place to live.

Arnold 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.

In Arnold, however, the average commute to work is quite long. On average, people spend 31.36 minutes each day getting to work, which is significantly higher than the national average.

If knowledge is power, Arnold is a pretty powerful place. 56.15% of the adults in Arnold have earned a 4-year college degree, masters degree, MD, law degree, or even PhD. Compare that to the national average of 21.84% for all cities and towns.

The per capita income in Arnold in 2022 was $59,231, which is upper middle income relative to Maryland, and wealthy relative to the rest of the US. This equates to an annual income of $236,924 for a family of four.
