Troy is a somewhat small city located in the state of Missouri. With a population of 13,951 people and five associated neighborhoods, Troy is the 62nd largest community in Missouri. Troy has seen a significant amount of newer housing growth in recent years. Quite often, new home construction is the result of new residents moving in who are middle class or wealthier, attracted by jobs, a healthy local economy, or other amenities as they leave nearby or far away areas for greener pastures. This seems to be the case in Troy, where the median household income is $74,463.00.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 8.00% 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.
