El uso de zonas censales para medir la segregación residencial. Contraindicaciones, propuesta metodológica y un estudio de caso: Argentina 1991-2001

Abstract

Attempts on measuring residential segregation using arbitrary spatial units constructed by census agencies carry certain drawbacks related to what is commonly known as the Modifiable Areal Unit Problem (MAUP). This problem has been generally ignored by urban researchers in this topic as if it would not affect the results of their studies. This paper discusses the legitimacy of using census zoning systems for measuring residential segregation, and proposes the use of data disaggregation and regrouping (DDR) techniques that may at some degree contribute in reducing MAUP biases. One of these techniques is used for measuring socioeconomic residential segregation trends in Argentina for the 1991- 2001 period. We conclude that in countries like Argentina these techniques represent just a partial and limited solution to MAUP. Uality and precision of quantitative studies on residential segregation and other fields dealing with similar problems may be substantially improved only if better access to spatially disaggregated data is provided by census agencies. © EURE.
