The two thematic issues 26(4) and 27(1) of Mathematical Population Studies deal with “methods and applications in spatial demography.” The five articles they contain, and which are listed below, show how population studies can be informed through an integration of appropriate spatial theory, data, and methods. In the editorial to appear in the next issue, 27(1), I will provide a summary of each article and discuss its contribution to this very lively field. I would like to thank the authors, the journal, and Taylor and Francis for these issues, which I had the pleasure of organizing. We wish you a pleasant reading.

空间人口学中的方法和应用

数学人口研究的两个主题问题 26(4) 和 27(1) 涉及“空间人口学中的方法和应用”。其中列出的五篇文章展示了如何通过整合适当的空间理论、数据和方法来了解人口研究。在下期第 27(1) 期的社论中，我将提供每篇文章的摘要，并讨论其对这个非常活跃的领域的贡献。我要感谢作者、期刊以及 Taylor 和 Francis 提出的这些问题，我有幸组织了这些问题。我们祝您阅读愉快。
