Statistics Finland has conducted five surveys concerning participation in adult education. The data for the first survey were collected in 1980. Since 1990 the survey has been conducted at about five-year intervals. Adult education surveys study participation in education, as well as learning and skills among the adult population. In addition, they produce data about people’s opinions and experiences of adult education, their willingness and need to participate in it, and obstacles to and preconditions for it. The population of the survey has been the resident adult population of Finland, defined in each survey as all persons aged 18 to 64 and living permanently in Finland. The data from the survey are based on face-to-face interviewing of a sample of approximately 5,000 people. The surveys have been joint projects with the Ministry of Education, which has also provided most of the funding for them. In addition, the 2006 survey is part of a European co-operative project co-ordinated by the Statistical Office of the European Communities (Eurostat).
