DIOC: Database on Immigrants in OECD countries and non-OECD Countries

Several years ago, the OECD started to compile data based on population censuses of OECD countries for the 2000 census round.

Since then, another round was added to the first one. And the OECD and the World Bank have joined their efforts in a project aimed at extending the coverage of the Database on Immigrants in OECD Countries (DIOC) to non-OECD destination countries (DIOC-E or DIOC extended). This data collection made it possible to calculate e‌migration rates by skill level.

The datasets include information on demographic characteristics (age and gender), duration of stay, labour market outcomes (labour market status, occupations, sectors of activity), fields of study, educational attainment and the place of birth.

DIOC contains information for the 34 OECD countries (destinations) and more than 200 countries of origin in the years 2000, 2005 and 2010. DIOC-E contains information for 100 destination countries and more than 200 countries of origin in the years 2000 and 2010.

The data is reconstructed primarily from census, and when not available from population registers and labor force surveys. The data includes segmentation by country of birth, nationality, gender, education level, age, duration of stay, labor force status and occupation.

The DIOC gives demographic and labour market characteristics data for 34 OECD member countries and 68 non-members in the year 2000. This database is being updated to the years 2010-2011 through a joint project between OECD, the World Bank and the International Migration Institute of the University of Oxford.
