The type of buildings and activities along the waterfronts have to stimulate the interactivity between public spaces and their users to reach the desired comfort, enjoyment and appropriate densities. This study is part of a continuing research and it aims to highlight the spatial relationship between the type of buildings and the densities on cities waterfronts of the Mediterranean Sea. It undertakes three case studies with different economic and touristic levels. It is a top-bottom approach that analyzes the existing population densities on waterfronts and the surrounding building functions. This paper uses quantitative analysis based on spatial statistics along each of the three waterfronts. The data collection is made through documentation, direct observations, mapping, Global Positioning System, and Geographic Information System software. The outcome of this research evaluates the relationship between functions and population densities to record how locations of functions increase population on waterfronts by making them attractive and recommends how waterfront zoning laws will consider specific land uses and techniques
