Key Largo is a somewhat small coastal town (i.e. on the ocean, a bay, or inlet) located in the state of Florida. With a population of 12,447 people and five associated neighborhoods, Key Largo is the 196th largest community in Florida.

Key Largo home prices are not only among the most expensive in Florida, but Key Largo real estate also consistently ranks among the most expensive in America.

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 an extremely popular vacation destination. A significant portion of the population is seasonal. During the vacation season, the town experiences a large influx of people who take up residence in second homes they own in the area. As the vacation season ends, the population drops again, leaving behind a substantially quieter and smaller town.

The town is relatively quiet, having a combination of lower population density and few of those groups of people who have a tendency to be noisy. For example, Key Largo has relatively fewer families with younger children, and/or college students. Combined, this makes Key Largo a pretty quiet place to live overall. If you like quiet, you will probably enjoy it here.

One of the nice things about Key Largo is that it is nautical, which means that parts of it are somewhat historic and touch the ocean or tidal bodies of water, such as inlets and bays.
