Immigration by category of entry Using new data recently compiled on permanent-type immigration according to the mode of entry, it is now possible to have a clearer idea of the nature of international immigration flows for a large number of OECD countries. Definition Immigrants here are defined as persons entering the resident population with a permit that is permanent or more or less indefinitely renewable. Also included are persons arriving on a long-term basis under a free-movement regime. Note that not all persons joining the resident population have actually entered the country during the data year shown. Some of them may have entered in a previous year on a temporary basis, such as international students, working holidaymakers, trainees, etc. and been subsequently granted the right to stay in the country on a long-term basis. These are known as "status changers”. Comparability The series shown are the first attempt to apply a standardised definition to statistics of international immigration. They are not, however, based on the definition specified in the United Nations Recommendations on International Migration Statistics (1998), which defines a long-term international migrant as a person who moves to a country other than that of his or her usual residence for a period of at least a year. This definition was not used because it is not possible to produce comparable statistics on this basis for very many countries. The statistics presented here are based on permit data, which may have a certain number of limitations. Not every international immigrant requires a permit. A permit may be granted in one year but used in another, it may never actually be used and in some cases, a person may receive more than one permit. However, the quality problems associated with these are likely to be small compared to the serious comparability problems associated with using published national statistics, whose coverage varies by as much as a factor of one to three. For certain countries in the accompanying table, the number of persons in the accompanying-family-of-worker category cannot be estimated separately and is included in the family-reunification column. For the OECD average, the two categories have been combined and the total appears in the family reunification column.
