The European Commission's Knowledge Centre on Migration and Demography (KCMD) ** Data+ catalogue** enables any user to discover datasets, web portals and platforms, stakeholder organisations, networks and forums as well as projects and Commission activities relevant to EU policies on migration and demography. It draws on a wide range of existing information sources. With key information, e.g. on content, methodology of collection, geographical and temporal coverage and frequency of update, this tool provides guidance on available datasets not only to EU policymakers but also to the public at large.
