IPUMS-International currently disseminates census microdata from 82 countries around the world. It’s an impressive collection. But it still only covers about half the world’s countries. Under the TerraPop project, we are working to assemble a truly comprehensive global collection of population data.
TerraPop recently launched TerraScope, a map-based portal for exploring the data in the TerraPop collection. The TerraPop collection includes census data from over 160 countries around the world, as well as environmental data describing land cover, land use, and climate. With such a broad range of data available, selecting a study area for which data are available to study a particular question or, conversely, determining the types of research questions that can be studied within an area of interest can be challenging.
Migration is a valuable adaptation strategy under certain conditions, but when the world’s poorest regions experience crop failures from drought or other climate events, international migration decreases. Why do climate events lead to increased migration in some places, but decreased migration in others?
