Ross, Claus-Thomas Bock, Boris-Alexander Ratsch, Claudia Kücherer, Norbert Bannert, Viviane Bremer, Osamah Hamouda, Ulrich Marcus, Ruth ZimmermannHomophily (Hx) in eight city samples (age, gender, HIV seroprevalence). Cities: Berlin (B), Essen (E); Leipzig (L); Frankfurt (F); Cologne (C); Hanover (H); Munich (M); Hamburg (HH). The homophily Hx shows the tendency of individuals in a group having social bonds with other individuals similar to them. Hx = 0 means that the formation of social bonds is independent of group membership. Hx=1 mean no social bonds to outsiders exist. Hx= -1 means all social bonds are formed with people outside the group [44]. (TIF 690 kb)
