Immigrants by Occupation (discontinued)

The sources for this database are mainly census data, from the 2000 round of censuses. Census data were used for 22 countries. Countries not taking periodic censuses but keeping population registers have provided data extracted from these registers; this is the case for four countries: Denmark, Finland, Norway and Sweden. For some countries, not all themes covered in the database are present in the national census or register. Labour force surveys, provided by Eurostat and averaged over the period 1998-2002, have been used to fill the gaps where possible.

本数据库的数据源主要取自2000年一轮的人口普查数据。其中22个国家采用了本国的人口普查原始数据。对于未开展定期人口普查但维护人口登记系统的国家，其数据从本国人口登记系统中提取；丹麦、芬兰、挪威、瑞典这四个国家即为此类情况。部分国家的全国人口普查或人口登记数据未能覆盖数据库所涵盖的全部主题，对此我们采用欧盟统计局（Eurostat）提供的劳动力调查数据，并以1998-2002年的期内平均值尽可能填补相关数据空缺。
