The Finnish Social Science Data Archive has published Open Access to and Reuse of Research Data—The State of the Art in Finland.
Here's an excerpt:
In 2006, the Ministry of Education in Finland allocated resources to the Finnish Social Science Data Archive (FSD) to chart national and international practices related to open access to research data. Consequently, the FSD carried out an online survey targeting professors of human sciences, social sciences and behavioural sciences in Finnish universities. Some respondents were senior staff at research institutes. The respondents were asked about the state and use of data collected in their department/institute. Almost half of the respondents considered the preservation and use of digital research data to be relevant to their department. The number of respondents (150) is large enough to warrant statistical analysis even though response rate was low at 28%.
