Social concepts, such as gender, class and ethnicity influence our everyday lives. Social geographers, therefore, pay attention to how these elements affect people and spaces. For example, think about how different people move through the city. Can everyone roam freely (as is the ideal in a modern free-society)? Or, are there barriers, both real and perceived? The redirecting of a traffic flow makes a road unsafe for children to play, an elderly person walks the long way around avoid a group of teenagers, a busker is moved along, a deaf person doesn’t go to the cinema because of a lack of subtitles. All these show how space is used, misused and controlled by people, groups, ideas and institutions.
