Proximity, or closeness, refers to the physical distance between two or more objects or entities. It can describe how near or far things are from each other in space. For example, the proximity of buildings in a city can affect how easily people can access services and amenities. In social contexts, proximity can influence relationships and interactions. People who live or work in close proximity often develop stronger connections due to frequent encounters. This concept is important in fields like urban planning and psychology, where understanding the effects of closeness can enhance community engagement and well-being.
