Lynbrook is a medium-sized village located in the state of New York. With a population of 20,071 people and four associated neighborhoods, Lynbrook is the 85th largest community in New York.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 15.29% 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.
