The present report, “Migration and health” is the most recent in a series of reports on challenges and trends in the health sector from the Directorate of Health. With this series, the Directorate aims to provide new insights into the health and care domain in order thereby to drive improvements and changes where they are needed. Part of our remit is to monitor developments in the Norwegian health service from a general societal perspective. This also enables us to identify challenges and the need for innovation and reform in our own domain and those of other authorities. The report directs attention at the diversity that exists in the Norwegian population and the challenges associated with health and interaction with the health service in Norway. The report is intended primarily for decision-makers, managers and employees in the health service. Other parties such as journalists, researchers and teaching staff will hopefully also find the report of use. “Migration and health” was compiled through a broad-based process within the Directorate, and with input from a number of external environments. We would like to convey our thanks to everyone who contributed to this report. (AU)
