Understanding the use of public space in high-density cities is a growing concern for designers and city officials. The world has been globalizing andurbanizing at fast speeds and today, over half of the world’s population lives in urban environments. High-density cities are a result of a large amount of people living in relatively close proximity to each other. The concentration of people in a small area creates smaller private space for people. Therefore, the public space will be utilized more and the design and use of public space has affects on the people and the city.Three urban parks were selected in the central core of Shanghai to observe the useof public space. Quantitative and qualitative analysis along with user surveys were conducted to create a better understanding of the performance and activities happening in the parks. The research found large amounts of people using the park during openhours. The park is more than a park for people and provides the space needed to perform activities. A list of design considerations were developed based on research and observations, such as more efficient uses of space.
