The historical population data for the Pennsylvania ZIP code 17855, which covers New Berlin, reveals a predominantly rural lifestyle and limited urban development activity over the past decade. With a land area of 1.95 square miles and a population that has fluctuated between 796 and 1,163 residents from 2010 to 2022, the population density has remained consistently within the range of 408 to 596 people per square mile.

This population density falls squarely within the rural classification, which is typically characterized by larger living spaces, fewer public services, and a community-oriented lifestyle centered around local schools and small businesses. The estimated 304 housing units corresponding to the 2022 population further support the presence of larger lot sizes and a more dispersed residential pattern, which is common in rural areas.

The relatively stable population numbers and the absence of significant population growth or decline suggest that the area has not experienced substantial urban development or demographic shifts over the past decade. This stability indicates that the lifestyle and land use patterns in the ZIP code have likely remained consistent, with a focus on outdoor activities, privacy, and a strong sense of community.
