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.

A relatively large number of people in Key Largo telecommute to their jobs. Overall, about 8.42% of the workforce works from home. While this may seem like a small number, as a fraction of the total workforce it ranks among the highest in the country. 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. The effect on the local economy is that many of the businesses are dependent on tourist dollars, and may operate only during the high 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.

Residents will find that the town is relatively quiet. This is because it is not over-populated, and it has fewer college students, renters, and young children - all of whom can be noisy at times. So, if you're looking for a relatively peaceful place to live, Key Largo is worth considering.

Key Largo 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.
