论文摘要
剥夺指数的构建因定义剥夺的固有歧义以及党派操纵的潜力而变得复杂。然而,剥夺指数为减轻剥夺的影响和通过政策干预措施减少剥夺的影响提供了必不可少的工具。在这里,我们证明了使用扩散图构建剥夺指数,这是一种流形学习技术,能够在保留数据点之间的成对关系的意义上找到最佳描述数据集中变化的变量。该方法适用于2010年美国十年人口普查。与其他方法相反,所提出的过程不会从人口普查中选择特定的列,而是构建了完整数据集中剥夺的指标。由于其构造,该提议的索引不会引入偏见,除了源数据中已经存在的索引,不需要关于某些生活方式的可取性规范性判断,并且对党派操纵的尝试具有很高的弹性。我们证明,新指数与既定的基于收入的剥夺指数都符合,但在某些现有指数中被认为是问题的方面偏离。所提出的程序为构建准确的高分辨率指数提供了一种有效的方法。因此,这些指数可能有可能成为社会结构学术研究以及政治决策的强大工具。
The construction of deprivation indices is complicated by the inherent ambiguity in defining deprivation as well as the potential for partisan manipulation. Nevertheless, deprivation indices provide an essential tool for mitigating the effects of deprivation and reducing it through policy interventions. Here we demonstrate the construction of a deprivation index using diffusion maps, a manifold learning technique capable of finding the variables that optimally describe the variations in a dataset in the sense of preserving pairwise relationships among the data points. The method is applied to the 2010 US decennial census. In contrast to other methods the proposed procedure does not select particular columns from the census, but rather constructs an indicator of deprivation from the complete dataset. Due to its construction the proposed index does not introduce biases except those already present in the source data, does not require normative judgment regarding the desirability of certain life styles, and is highly resilient against attempts of partisan manipulation. We demonstrate that the new index aligns well with established income-based deprivation indices but deviates in aspects that are perceived as problematic in some of the existing indices. The proposed procedure provides an efficient way for constructing accurate, high resolution indices. These indices can thus have the potential to become powerful tools for the academic study of social structure as well as political decision making.
