Community Demographic Model International Migration (CDM-IM) Dataset : Generating Age and Gender Profiles of International Migration Flows

However, information on international migrant's demographic characteristics is sparse. To develop the multiregional population/urbanization projections module of the NCAR Community Demographic Model (CDM) requires information on the age and gender composition of international migration streams.

This paper reports on the methods used to generate the CDM International Migration dataset, which contains information on the age and gender profiles of international migrants with approximate global coverage. We use the raw data from the United Nations Global Migration Database (UNGMD) to derive the highest quality migrant stock for two time points closest to the year 2000. We reallocate the migrants into standardized age and gender categories by using information directly from the selected file, by borrowing information from files of other years, and by applying aggregated region-level information.
