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.

Telecommuters are a relatively large percentage of the workforce: 21.78% 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 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", which are people who are not only wealthy and employed in professional occupations, but highly educated to boot.

Urban sophisticates support bookstores, quality clothing stores, enjoy luxury travel, and in big cities, they are truly the patrons of the arts, attending and supporting institutions such as opera, symphony, ballet, and theatre.

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.
