Sussex is a somewhat small village located in the state of Wisconsin. With a population of 11,819 people and four associated neighborhoods, Sussex is the 83rd largest community in Wisconsin.

Sussex real estate is some of the most expensive in Wisconsin, although Sussex house values don't compare to the most expensive real estate in the U.S.

Also of interest is that Sussex 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: 16.20% 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, Sussex 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, Sussex really has some of the features that families look for when choosing a good community to raise children. Is Sussex 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.

The education level of Sussex ranks among the highest in the nation. Of the 25-and-older adult population in Sussex, 47.66% have at least a bachelor's degree. The typical US community has just 21.84% of its adults holding a bachelor's degree or graduate degree.
