Abstract

"This paper addresses itself to one of the problems inherent in any spatial analysis of census data, namely the variable size of the enumeration units. This variation renders some proportions unstable, due to the small numbers involved. Attempts to overcome this, using visual methods, can be unsatisfactory, whilst doing nothing to aid statistical analysis. Chi-square maps are suggested as a satisfactory alternative in both contexts, and data for Reading, Berkshire are displayed to illustrate this. These maps suggest that some inferences, based upon indicators derived from proportions, may be unsound."

摘要

本文探讨了人口普查数据空间分析中固有的一个问题，即普查单位规模的变化。由于涉及的数量较少，这种变化使得一些比例不稳定。试图通过视觉方法克服这一问题可能并不令人满意，同时对统计分析也毫无帮助。在这两种情况下，卡方地图被认为是一种令人满意的替代方法，并展示了伯克郡雷丁的数据以作说明。这些地图表明，基于比例得出的指标所做的一些推断可能是不可靠的。
