Millville is a very small coastal town (i.e. on the ocean, a bay, or inlet) located in the state of Delaware. With a population of 2,108 people and two associated neighborhoods, Millville is the 27th largest community in Delaware. Much of the housing stock in Millville was built relatively recently. The construction of new real estate can often be taken as an indication that the local Millville economy is robust, and that jobs or other amenities are attracting an influx of new residents. This seems to be the case in Millville, where the median household income is $99,776.00.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 30.94% 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 Millville 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.

In addition, Millville is home to many people who could be described as "urban sophisticates". Urban sophisticates are people who are both educated and wealthy, and thus tend to be older, richer, and more established than young professionals. "Urban sophisticates" is not just about being educated and well-off financially: it is a point of view and state of mind, one that you might call 'urbaneness'. But such people can and do regularly live in small towns, suburbs and rural areas, as well as in big cities. They read, support the arts and high-end shops, and love travel.

Millville 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. Such areas are often places that visitors and locals go for waterfront activities or taking in the scenery.
