隔离通常通过相异性指数来衡量。最近制定了一个“边界修改”版本的指数。它基于这样一个概念，即隔离是由强加于社会空间的空间结构造成的分离，因此种族群体之间的互动是有限的。该索引考虑了空间元素之一--连续性--但忽略了其他元素。本文认为，两个面积单元之间的公共边界的长度和面积单元的形状是重要的空间成分，在确定隔离。因此，通过合并这些空间分量推导出一系列分离指数，并且可以应用于各种空间配置。其中一个指数具有独特的属性，这是有用的，在不同尺度的区域中的隔离水平进行比较。
Segregation is commonly measured by means of an index of dissimilarity. A recent 'boundary modified' version of the index was formulated. It was based upon the concept that segregation is a separation created by spatial structure imposed upon the social space and thus interaction between racial groups is limited. The index takes into account one of the spatial elements-contiguity-but ignores the others. This paper argues that the length of the common boundary between two areal units and the shape of the areal units are important spatial components in determining segregation. Thus, a family of segregation indices is derived by incorporating these spatial components and can be applied to various spatial configurations. One of the indices possesses a distinctive property which is useful for comparing segregation levels in regions of various scales.
