种族多样性和居住隔离的空间格局的变化往往是高度局部性的，但不同时间点的地理数据单位的不一致限制了它们的探索。在这篇文章中，我们认为，尽管人口网格经常被忽视，但它为研究长期细尺度变化提供了一种有效的手段。网格数据代表人口结构：没有人口的地方有缺口，而且(与标准区域不同)它们不是基于任何一个时间点的人口分布。这份白皮书使用了一个创新的资源，PopChange，它提供了关于出生国(1971-2011年)和族裔(1991-2011年)的空间细粒度(1×1千米×1千米)网格数据。这些数据使人们能够洞察很长一段时间内的微观变化。在五个时间点上探索40年来的变化，这里使用了居住种族多样性和种族隔离的衡量标准，创建了整个英国种族社区变化的综合“地图集”。报告提供了四个关键信息：(1)随着英国种族多样性的增加，这种多样性的空间复杂性也增加了，以前不那么多样化的空间的多样性更大；(2)在这一微观尺度上，种族居住隔离正在稳步下降；(3)随着社区变得更加多样化，它们在空间上变得更加一体化；(4)在整个研究期间，变化最活跃的时期是2001至2011年。本文以英国为例，探讨了网格化数据所提供的潜力，并提出了分析这些数据的方法，以供该研究领域内外未来的联合研究之用。
Changes in the spatial patterns of ethnic diversity and residential segregation are often highly localized, but inconsistencies in geographical data units across different time points limit their exploration. In this paper, we argue that, while they are often over-looked, population grids provide an effective means for the study of long-term fine-scale changes. Gridded data represent population structures: there are gaps where there are no people, and they are not (unlike standard zones) based on population distributions at any one time point. This paper uses an innovative resource, PopChange, which provides spatially fine-grained (1 km by 1 km) gridded data on country of birth (1971–2011) and ethnic group (1991–2011). These data enable insight into micro-level change across a long time period. Exploring forty years of change over five time points, measures of residential ethnic diversity and segregation are employed here to create a comprehensive ‘atlas’ of ethnic neighbourhood change across the whole of Britain. Four key messages are offered: (1) as Britain’s ethnic diversity has grown, the spatial complexity of this diversity has also increased, with greater diversity in previously less diverse spaces; (2) ethnic residential segregation has steadily declined at this micro-scale; (3) as neighbourhoods have become more diverse, they have become more spatially integrated; (4) across the whole study period, the most dynamic period of change was between 2001 and 2011. While concentrating on Britain as a case study, the paper explores the potential offered by gridded data, and the methods proposed to analyse them, for future allied studies within and outside this study area.
