title: [Confronting the statistics on intra-European migration:  toward greater harmonization?].
abstract: "Each international migration stream can be enumerated twice:  at the time of departure from the country of emigration and at the time of arrival in the country of immigration.  In practice, errors in international migration statistics are a major obstacle to the accurate analysis of migration flows.  In connection with the process of harmonization set in train by Eurostat several years ago, a method of correcting defective migration data is proposed here, which makes use of this double enumeration.  The method is applied to available data in a preliminary analysis.  The correction factors presented here through this mathematical approach should turn out to be useful in more than one respect:  to illuminate substantial problems of incompatibility of migration data and to follow the progress of the harmonization of those data."
