Through this joint publication, IMP and UNFPA are providing readers with an overviewin an accessible and user-friendly mannerof the salient developments in migration, primarily international migration, since the adoption of the ICPD PoA 10 years ago. It also points to some of the challenges ahead in the coming years. In doing so, it draws on migration-related fi ndings described in the UNFPA Report, Investing in People: National Progress in Implementing the ICPD Programme of Action 1994-2004, the results of which are based on the 2003 Global Survey sent to 187 countries to assess progress on all ICPD PoA recommendations since 1994. Meeting the Challenges of Migration: Progress Since the ICPD goes into greater depth on migration developments focusing on: migration trends; migration policy developments; migration and development; migration and human rights; economic migration; refugee protection; human trafficking; internal migration; and migration data. Meeting the Challenges of Migration: Progress Since the ICPD is by no means an exhaustive study nor does it pretend, by this limited volume, to explore the depths of the topics covered. Rather, it draws out a select number of migration issues where considerable developments have occurred since 1994. Meeting the Challenges of Migration: Progress Since the ICPD should be of interest to migration practitioners and academics but also to others working on international issues affecting and/or affected by human mobility.
