The practice of installing residential street barriers (RSBs) has become widespread in Jakarta. Although RSBs are a most common and familiar manifestation of a collective sense of insecurity in the city, the phenomenon has received scant scholarly attention. This paper presents the first comprehensive study of RSBs in Jakarta. It examines the diversity of the socioeconomic background of communities with the desire to create RSBs. The study finds that the cross-class spread of RSBs is characterized by: (1) a general pattern of inner-city-concentric distribution; (2) sparsely located local contagion spots; and (3) the coexistence of crime-related and traffic-related concerns. Finally, such spatial patterns are discussed in light of the recent socio-spatial changes in the city.
