The Integrated European Population Microdata (IEPM) database is under construction. With the funding by the National Institutes of Health (NIH) of the United States, integration and full documentation of the data are being organized by the Minnesota Population Center. In addition, the Centre d'Estudis Demogràfics (CED) has been successful in attracting European Union research programmes support for enhancing, harmonizing and disseminating the integrated European microdata and metadata as well as for coordinating tasks based in Europe.
