That's a reasonable first approximation.

However, I would add that attempts are a poor indicator because there is a wide range of methods with poor success rates. EX: An increasing in attempts can relate to people choosing low success rate methods and failing.

Also younger people are far more likely to commit suicide than the elderly or vary young. However, generally employed people tend to have lower suicide rates. There is also a significant gender bias in suicide attempts and different bias in rates of suicide. Men are more likely to die on their first attempt in large part due to their chosen methods etc.

Also, suicides rates tend to cluster more than expected, both in the short and long term.
