In this paper, we compare estimates of population attraction and retention, or rather, internal migration, based on three datasets: the long-form Census of Canada, the Longitudinal Administrative Databank (LAD), and the Medicare Client Registry. We find that the administrative data sources (especially the LAD) produce much higher rates of internal migration than the Census, and that the Census and Medicare Client Registry are more closely aligned when it comes to estimating internal migration. We discuss the strengths and limitations of each approach and conclude with some recommendations for appropriate usage of all three files.

什么是新不伦瑞克省的内部迁移率？：取决于数据来源

在本文中，我们比较了基于三个数据集的人口吸引和保留，或者更确切地说是内部迁移的估计：加拿大的长期人口普查、纵向行政数据库 (LAD) 和医疗保险客户登记处。我们发现行政数据源（尤其是 LAD）产生的内部迁移率比人口普查要高得多，而且在估计内部迁移时，人口普查和医疗保险客户登记处更加一致。我们讨论了每种方法的优点和局限性，最后提出了一些关于正确使用所有三个文件的建议。
