However, the Annual Health report 2012 indicates that since 1990, suicides have decreased in every age group except among 15-24 year-olds, where it has become somewhat more common, reflecting the overall trend of increasing mental ill health amongst youth in Sweden. On the other hand, suicide rates have declined the most among senior citizens, especially among men, and differences between the age groups have decreased. Differences between levels of education are more significant among men: the number of men holding a lower secondary level degree is twice as high as those with a post-secondary education.
