Adult Education Surveys have been conducted at Statistics Finland since 1980 at intervals of around five years. From 2006, the survey has been carried out as part of the Adult Education Survey project of Eurostat, the Statistical Office of the European Communities, for which data are collected in some 30 European countries. In Finland, the survey has been implemented as a joint project between Statistics Finland and the Ministry of Education and Culture. Adult Education Surveys have examined participation in education, learning and skills among the adult population. In addition, data have been produced on adults’ opinions and attitudes concerning studying, willingness and need to participate in education and obstacles to and conditions for participation. The population of the survey has been Finland’s resident adult population. The adult population has been defined in each survey as all persons aged 18 to 64 and living permanently in Finland. The survey data are based on face-to-face interviews implemented by means of a sample of around 5,000 persons.
