本文详细介绍了一种创新的方法,该方法能够分析小区域人口在40年内的变化。人口表面是使用1971年至2011年(包括1971年至2011年)每次人口普查的小区域数据(枚举区或输出区)生成的。本文详细介绍了在创建这些表面时使用的方法,并讨论了这种方法背后的基本原理,认为网格是评估人口分布的最合适的模型。以北爱尔兰现有的人口网格为基准,对网格创建方法进行了测试。开发的方法随后被应用于创建1971年、1981年、1991年、2001年和2011年英国其他地区的人口网格。这里探讨了这五个时间点上小地区不断变化的人口结构,以说明这种方法的价值。公众可获得的数据资源--‘PopChange’项目的最终产品--将有助于探索小区域内人口的长期变化。这篇论文认为,如果以类似的方式对这些数据进行网格化,使用PopChange项目提供的工具,将它们置于更长期的历史背景中,就可以最大限度地利用“大数据革命”。(C)2017年作者。爱思唯尔有限公司出版。
This paper details an innovative approach which enables the analysis of small area population change across four decades. Population surfaces are generated using small area data (enumeration districts or output areas) for each Census from 1971 to 2011 inclusive. The paper details the methods used in the creation of these surfaces, and discusses the rationale behind this approach, arguing that grids represent the most appropriate model for assessing population distributions. Methods for grid creation are tested using pre-existing population grids for Northern Ireland as a benchmark. The method developed is then applied to create population grids for the rest of the UK for 1971, 1981, 1991, 2001 and 2011. The changing population structures of small areas across these five time points are explored here to illustrate the value of this approach. The publically-available data resource - the final product of the 'PopChange' project - will facilitate exploration of long-term changes in populations over small areas. The paper argues that maximum advantage could be taken of the 'big data revolution' if such data were gridded in a similar way, allowing them to be placed in a longer-term historical context, using tools made available through the PopChange project.
