Petersburg is a very small city located in the state of Indiana. With a population of 2,260 people and two associated neighborhoods, Petersburg is the 220th largest community in Indiana. Petersburg has a large stock of pre-World War II architecture, making it one of the older and more historic cities in the country.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 7.60% 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.

It is a fairly quiet city 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!) Petersburg 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. Petersburg has few renters and college students. But the biggest reason it is quieter in Petersburg than in most places in America, is that there are just simply fewer people living here. If you think trees make good neighbors, Petersburg may be for you.

As is often the case in a small city, Petersburg doesn't have a public transportation system that people use for their commute.

In Petersburg, just 12.22% of people have at least a bachelor's degree, which is quite a bit lower than the national average for cities and towns of 21.84%.

The per capita income in Petersburg in 2022 was $30,907, which is middle income relative to Indiana, and lower middle income relative to the rest of the US. This equates to an annual income of $123,628 for a family of four. However, Petersburg contains both very wealthy and poor people as well.
