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.

Millville home prices are not only among the most expensive in Delaware, but Millville real estate also consistently ranks among the most expensive in America.

Also of interest is that Millville 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: 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 educated, wealthy, executives and professionals, who have urbane tastes in books, food, and travel, whether they actually live in a big city, or choose to reside in a small town. In big or medium-sized cities, urban sophisticates tend to frequent art institutions such as opera, symphonies, ballet, live theatre, and museums.

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. Quite often, nautical areas such as these attract visitors and locals who come to enjoy the scenery and various waterfront activities.

Millville is one of the most well-educated cities in the nation. 43.51% of adults in Millville have at least a bachelor's degree. Compare that to the average community in America, which has just 21.84% with a bachelor's degree or higher.

The per capita income in Millville in 2022 was $65,560, which is wealthy relative to Delaware and the nation. This equates to an annual income of $262,240 for a family of four.
