Petersburg is a very small town located in the state of New York. With a population of 3,144 people and two associated neighborhoods, Petersburg is the 460th largest community in New York. Petersburg has a large stock of pre-World War II architecture, making it one of the older and more historic towns in the country.

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

One interesting thing about the economy is that relatively large numbers of people worked from their home: 11.24% 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.

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, Petersburg has relatively fewer families with younger children, and/or college students. Combined, this makes Petersburg a pretty quiet place to live overall. If you like quiet, you will probably enjoy it here.

In Petersburg, however, the average commute to work is quite long. On average, people spend 31.13 minutes each day getting to work, which is significantly higher than the national average.

The education level of Petersburg citizens is a little higher than the average for US cities and towns: 21.69% of adults in Petersburg have at least a bachelor's degree.

The per capita income in Petersburg in 2022 was $38,404, which is middle income relative to New York, and upper middle income relative to the rest of the US. This equates to an annual income of $153,616 for a family of four. However, Petersburg contains both very wealthy and poor people as well.
