how can I download count of migration between departments in Colombia (using the before 5 years residence)?
There are several different ways to measure the count of migration across department boarders in Colombia. The specific variables you end up using will largely depend on the years included in your sample. As you can see here, there are several migration variables available for the Colombia samples, but non are available for all years.
Once you specify your sample years and choose which variables you’d like to include in your data extract, you can download these variables through the “Data Cart” on the IPUMS site.
