Avalon is a very small borough located in the state of Pennsylvania. With a population of 4,644 people and two associated neighborhoods, Avalon is the 322nd largest community in Pennsylvania. Avalon has an unusually large stock of pre-World War II architecture, making it one of the older and more historic boroughs.

Also of interest is that Avalon has more people living here who work in computers and math than 95% of the places in the US.

Of important note, Avalon is also a borough of artists. Avalon has more artists, designers and people working in media than 90% of the communities in America. This concentration of artists helps shape Avalon’s character.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 13.64% 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.

Despite the fact that it is a small borough, Avalon has quite a few people who take public transportation – mostly the bus - for their daily commute to work. This helps to fill a real need in the borough for affordable transportation.

The overall education level of Avalon citizens is substantially higher than the typical US community, as 32.79% of adults in Avalon have at least a bachelor's degree, and the average American community has 21.84%.

The per capita income in Avalon in 2022 was $37,246, which is upper middle income relative to Pennsylvania and the nation. This equates to an annual income of $148,984 for a family of four. However, Avalon contains both very wealthy and poor people as well.
