This paper examines features of residential segregation in five mixed Arab-Jewish cities in Israel; the role of ideology and state politics among the charter group—i.e. the Jewish population—is considered to be a dominant factor in this social process. Utilising available Israeli census data supplemented by the author's own field survey, the study indicates that all five cities have experienced a continuous trend of high indices of segregation and hypersegregation. The spatial manifestation of this trend is a classic display of sectoral (but not concentric) patterns of residency. Concomitantly, the scope of both social and economic interactions between the two communities sharing the same urban space remains underdeveloped. The city has effectively provided a sense of local identity: both groups live in and are part of the same place, yet this space is not a locus for genuine integration. A situation of neighbours without neighbourly relations marks the residential reality of Israeli mixed cities.
