鉴于生育率和死亡率呈下降趋势，人口动态-因此，对空间上明确的人口动态和网格化人口及衍生产品的估计-对流动过程及其空间变化越来越敏感。在本文中，我们提出了一个程序，以产生出发地-目的地城际/县际和州际迁移矩阵，简要讨论了它们的使用和网格人口产品的应用。为了说明我们的方法，我们从2000年和2010年墨西哥人口普查长式10%调查的信息制作总矩阵和性别矩阵。我们分享了重新提取这些数据所需的代码，并基于IPUMS International（IPUMS国际）或IPUMS Terra（IPUMS Terra）的统一公开数据，至少在另外122个国家时期内进行提取，IPUMS国际允许添加辅助社会和经济数据以及个人和家庭层面的数据，IPUMS Terra进一步允许基于GIS的映射，可视化和操作，并合并重要的上下文，例如，环境数据除了讨论这些措施可能存在的局限性，使用墨西哥政府的官方预测，我们说明了移民/流动性数据如何提高空间/网格人口动态的估计。最后，我们呼吁收集关于全球居住流动性和移民的更充分、更明确的空间数据。数据集：作为补充文件提供。数据集许可证：CCBY 4.0
Given downward trends in fertility and mortality, population dynamics -and thus the estimation of spatially-explicit population dynamics and gridded population and derivative products- are increasingly sensitive to mobility processes and their changes in spatiality. In this paper, we present a procedure to produce origin-destination intermunicipal/intercounty and interstate migration matrices, briefly discussing their use and application in gridded population products. To illustrate our approach, we produce total and sex-specific matrices with information from the 2000 and 2010 Mexican Census long-form 10% surveys. We share the code required to reproduce the extraction of these and for potentially at least another 122 country-periods based on harmonized publicly-available data from IPUMS International, which allow for the addition of ancillary social and economic data and individual and household levels, or IPUMS Terra, which further allow for GIS-based mapping, visualization, and manipulation and for the merging of important contextual, e.g., environmental, data. Besides discussing the likely limitations of these measures, using official projections from the Mexican government, we illustrate how migration/mobility data improve the estimation of spatial/gridded population dynamics. We wrap up with a call for the collection of more adequate, spatially-explicit data on residential mobility and migration globally. Dataset: available as the supplementary file.
