International migration policies and data

Database on immigrants in OECD and non-OECD countries (DIOC-E)

 

(RELEASE 3.0    27/09/2011)

Several years ago, the OECD compiled data based on population censuses of OECD countries for the 2000 census round, which included information on demographic characteristics (age and gender), duration of stay, labour market characteristics (labour market status, occupations, sectors of activity), fields of study, educational attainment and place of birth. These data on migrant stocks in OECD countries can be downloaded from www.oecd.org/migration/dioc.


The increasing importance of South-South migration flows, however, makes it necessary to pay more attention to immigrant populations in a number of key destination countries outside the OECD. The OECD and the World Bank have therefore joined their efforts in a project aimed at extending the coverage of the Database on Immigrants in OECD Countries to non-OECD destination countries for the year 2000.

  

This new global bilateral international migration database DIOC-E helps refining and challenging previous conclusions of international migration patterns. The recent OECD Working Paper “International Migrants in Developed, Emerging and Developing Countries: An Extended Profile” provides a first overview of DIOC-E (release 2.0) regarding the characteristics of immigrant and emigrant populations, new estimates of the “brain drain” and first analyses of the selectivity of migration distinguishing migration to the OECD and to non-OECD destinations.

 

DIOC-E (release 3.0) currently covers 32 OECD and 68 non-OECD destination countries as well as 233 countries of origin. These data have made it possible to produce new estimates of emigration rates by all skill levels for around 162 countries of origin. These estimates are based on more accurate education data for origin countries, which were harmonized according to the International Standard Classification of Education (ISCED 1997).

The data files of DIOC-E can be downloaded free of charge:

Data for Latin American countries included in DIOC-E (release 3.0) were compiled by the OECD Development Centre for the Latin American Economic Outlook 2010 (www.oecd.org/dev/publications/leo) following the methodology established by the Database on Immigrants in OECD Countries (DIOC), produced and maintained by the OECD Directorate of Employment, Labour and Social Affairs (DELSA). The extension of the DIOC methodology to these Latin American countries was a collaborative effort of the Development Centre and DELSA.
