A public park is indeed considered to be a public good. This classification stems from two primary characteristics inherent to public goods: non-excludability and non-rivalry.
Firstly, public parks are non-excludable. This means that once a park is established, it is open for anyone to use without restrictions. People cannot be easily barred from entering the park, which allows everyone in the community the opportunity to enjoy the space regardless of their socioeconomic status.
Secondly, public parks are non-rivalrous. The use of a park by one person does not diminish the ability of others to use it as well. For example, if one person is walking their dog in the park, it does not prevent others from running, playing, or relaxing there simultaneously. This shared use is a key feature of public goods.
In addition to these characteristics, public parks also provide significant social benefits. They offer a space for recreation, relaxation, and community gatherings, contributing to the overall well-being of the community. This enhances social cohesion and promotes a healthier lifestyle among residents.
However, it’s worth noting that maintaining public parks requires funding and resources, typically provided by local governments. If investments are inadequate, the quality and accessibility of these parks may decline, potentially leading to a situation where they are less accessible or enjoyable. Nonetheless, as long as the park remains accessible to all and its use does not deplete its availability, it holds strong status as a public good.
