Abstract
Given downward trends in fertility and mortality, population dynamics –and thus theestimation of spatially-explicit population dynamics and gridded population and derivativeproducts– are increasingly sensitive to mobility processes and their changes in spatiality. In thispaper, we present a procedure to produce origin-destination intermunicipal/intercounty andinterstate migration matrices, briefly discussing their use and application in gridded populationproducts. To illustrate our approach, we produce total and sex-specific matrices with informationfrom the 2000 and 2010 Mexican Census long-form 10% surveys. We share the code required toreproduce the extraction of these and for potentially at least another 122 country-periods based onharmonized publicly-available data from IPUMS International, which allow for the addition ofancillary social and economic data and individual and household levels, or IPUMS Terra, whichfurther allow for GIS-based mapping, visualization, and manipulation and for the merging ofimportant contextual, e.g., environmental, data. Besides discussing the likely limitations of thesemeasures, using official projections from the Mexican government, we illustrate howmigration/mobility data improve the estimation of spatial/gridded population dynamics. We wrapup with a call for the collection of more adequate, spatially-explicit data on residential mobility andmigration globally.

With a “natural” population increase, i.e., that is due to the net effect of fertility and mortality, on the decline around much of the world, the quantification of social growth, i.e., migration and residential mobility spanning administrative boundaries, is becoming an increasingly relevant quantity used to accurately estimate current and future spatial population distributions [1,2], and other gridded products
This is true as migration impacts gridded population products when its magnitude changes, and when its spatial distribution shifts
Summary
With a “natural” population increase, i.e., that is due to the net effect of fertility and mortality, on the decline around much of the world, the quantification of social growth, i.e., migration and residential mobility spanning administrative boundaries, is becoming an increasingly relevant quantity used to accurately estimate current and future spatial population distributions [1,2], and other gridded products. This is true as migration impacts gridded population products when its magnitude changes, and when its spatial distribution shifts These data have been harmonized and are publicly available from IPUMS-International [3], and can be merged into a Geographic Information System via the IPUMS-Terra system [4]. (Alternatively, readers might want to use a broader set of harmonized migration measures from the IMAGE Project [5], which includes flows from the IPUMS collection plus several additional estimates based on nationally-representative survey or population register data, but for which no sex-specific detail or ancillary social and economic information is available.) We wrap up by briefly describing some applications of these data, placing special emphasis on the estimation of changes in gridded population distributions, both in Mexico and beyond
