One interesting thing about the economy is that relatively large numbers of people worked from their home: 8.42% 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 Key Largo is a major vacation destination. Much of the town’s population is seasonal: many people own second homes and only live there part-time, during the vacation season.

As the vacation season ends, Key Largo’s population drops significantly, such that year-round residents will notice that the city is a much quieter place to live.

It is a fairly quiet town because there are relatively few of those groups of people who have a tendency to be noisy. (Children, for example, often can't help themselves from being noisy, and being parents ourselves, we know!) Key Largo has relatively few families with children living at home, and is quieter because of it. Renters and college students, for their own reasons, can also be noisy. Key Largo has few renters and college students. But the biggest reason it is quieter in Key Largo than in most places in America, is that there are just simply fewer people living here. If you think trees make good neighbors, Key Largo may be for you.
