The differences in attitudes towards a fifth nuclear power plant within population groups are great, in the same way as before. There is distinctly more understanding for the project among men (60% supporting, 23% opposing) than among women (27%/51%). This contrast reflects the fact that the construction decision in principle clearly pleased more men than women. The difference according to gender has been great throughout the follow-up period [Figure 5.].

In older population groups opinions are clearly more positive. Dependency on age to that effect - i.e. the younger the respondent, the more negative the attitude - has been clearly distinguished in the material of the last few years. In the early years of the follow-up and in the material about ten years ago, opinions regarding nuclear power were not at all tied to age.

The connection with the level of education has also changed to a certain degree over time. Although support for nuclear power still increases along with the rise in the level of education, this dependency is weaker than in the early part of the follow-up period. In terms of nuclear power acceptance, those with academic education differ clearly from others in the present results. The connection with the education level is also clearly a gender-related phenomenon: with men, positive attitudes towards nuclear power strongly increase along with a rise in their level of education, whereas women's opinions on nuclear power are quite independent of their level of education (no figure).

Among different occupational and social groups, those in a leading position, managers and professionals, as well as entrepreneurs, are most in favour of nuclear power. Politically, the supporters of the National Coalition Party (67%) are distinctly more positive about nuclear power than the others. The project also has above-average acceptance among the supporters of the Social Democratic Party and the Centre Party. As usual, the supporters of the Green League have the most anti-nuclear power attitudes. As a supplementary detail from outside the figure, it can be mentioned that the Swedish-speaking population is more anti-nuclear than the Finnish-speaking citizens.

The population of the municipalities in which nuclear power plants are already located are clearly more positive about the building of additional nuclear power capacity than people elsewhere in the country - in the same way as in the previous results. Supporters of a fifth nuclear power plant constitute a significant majority in both Loviisa (69%) and Eurajoki (60%). In comparison with the previous measurement, the development of attitudes in the two municipalities takes different trends. Positive attitudes in Loviisa seem to be even more widespread, while signs of increased reservations are observed in Eurajoki. The latter change becomes softer if previous development of attitudes is observed in the interpretation. The 'demand' for a new plant saw a strong increase in Eurajoki for several years. The most recent result for the municipality does not significantly deviate from the results in 2001 and 2002. One can also think that the commencement of the construction project brings a certain degree of confusion to the local society and its established patterns of life. Statistical factors must naturally be kept in mind when assessing the municipality-specific results: figures calculated on relatively small groups of respondents must always be observed with a certain degree of slackness [Figure 6.].
