The paper compares and contrasts internal migration measured by healthcard-based administrative data with census figures. This is useful because the collection of population data, its processing, and its dissemination by statistical agencies is becoming more reliant on administrative data. Statistical agencies already use healthcard data to make migration estimates and are increasingly confident about local population estimates from administrative sources. This analysis goes further than this work as it assesses how far healthcard data can produce reliable data products of the kind to which academics are accustomed. It does this by examining migration events versus transitions over a full intercensal period; population flows into and out of small areas; and the extent to which it produces microdata on migration equivalent to that in the census. It is shown that for most demographic groups and places healthcard data is an adequate substitute for census-based migration counts, the exceptions being for student households and younger people. However, census-like information is still needed to provide covariates for analysis and this will still be required whatever the future of the traditional census.

管理数据如何与人口普查数据进行比较以衡量内部迁移?北爱尔兰案例,2001-2011年

本文将基于健康卡的行政数据与人口普查数据进行了比较和对比。这是有用的,因为人口数据的收集,处理以及统计机构的分发越来越依赖于行政数据。统计机构已经使用医疗卡数据进行移民估计,并且对从行政渠道获得的当地人口估计越来越有信心。这种分析比这项工作更进一步,因为它评估了医疗卡数据可以产生多大程度的学者习惯的可靠数据产品。它通过检查整个迁移期间的迁移事件与转换之间的关系来做到这一点;人口流入和流出小区域;以及它在迁移方面产生的微数据的程度与普查中的结果相当。结果表明,对于大多数人口群体和地方,医疗卡数据可以替代基于人口普查的移民计数,但学生家庭和年轻人除外。但是,仍需要类似普查的信息来提供协变量进行分析,而无论传统普查的未来如何,仍将需要这种信息。
