Factors such as having family in the neighborhood and interaction with neighbors have been found to provide a contextual understanding of why people stay in a neighborhood. But according to a Pew Research Center (2010) study, fewer than half of American adults (43 percent) know most or all of their neighbors. In his book The Vanishing Neighbor, Marc Dunkelman (2014) argues that technology coupled with new routines of everyday life have expanded the breadth of our social landscapes while at the same time, eroding the incidental interactions that have built local communities for centuries. The shared courtyards of Copenhagen’s residential buildings  foster an environment that encourages residents to meet each other and build social connections. Playgrounds, barbeque areas, picnic tables, and elevators placed in a central location provide opportunities for residents to pass by one another.
