Demographic Changes in Central PA Cities and Major Towns
April 2016
Category: Location

"Downtown" and "Main Street" are terms that we often hear that refers to the core business or commercial area of cities and towns. These terms have become buzzwords that are used to help brand a place where economic development is occurring. It's a place where businesses want to be and people want to live, work, and play. Many studies have suggested that the demographics of cities are shifting or are likely to shift in the future. The Millennial crowd will find these places attractive since they are more likely to be renters than homeowners, as well as because of convenience and lifestyle. These studies have also suggested that it is likely you will see a larger Baby Boomer population selling their homes in the suburbs and moving into the cities for some of the same similar reasons. These shifts and changes in the demographics will definitely have an impact on the future of cities and major towns.
In this analysis, we wanted to quantify some of the demographic changes we have seen in a set of Central Pennsylvania's cities and major towns and also some of the changes we are likely to witness over the next five years.
