When addressing real world problems in international migration research, invariably the topic of migration-related policy comes to the fore. Policies may look to address specific issues such as the integration of migrants, but in most cases they can be boiled down to limiting the flows of some types of migrant or encouraging the flows of others. Judging the impact of both migration flows and migration policy can only be done effectively with good information, but too often data on migration are poor and thus the evidence base lacking.
