This paper provides a comparative assessment of income segregation within cities in 12 countries. We use spatial entropy indexes based on small-scale gridded income data and consistent definition of city boundaries to ensure international comparability of our segregation measures. Results show considerable variation in the levels of income segregation across cities, even within countries, reflecting the diversity of cities within urban systems. Larger, more affluent, productive, and more unequal cities tend to be more segregated. Urban form, demographic, and economic factors explain additional variation in segregation levels through the influence of high-income households, who tend to be the most segregated. The positive association between productivity and segregation is mitigated in polycentric cities.

分裂的城市有什么共同点？收入隔离的国际比较

本文对 12 个国家城市内的收入隔离进行了比较评估。我们使用基于小规模网格收入数据和一致定义的城市边界的空间熵指数，以确保我们的隔离措施的国际可比性。结果表明，不同城市的收入隔离水平存在很大差异，甚至在国家内部也是如此，这反映了城市系统内城市的多样性。更大、更富裕、生产力更高和更不平等的城市往往更加隔离。城市形态、人口和经济因素通过高收入家庭的影响解释了隔离水平的额外变化，他们往往是最隔离的。在多中心城市中，生产力与种族隔离之间的正相关关系得到缓解。
