Isn't this female rate increasing faster than the male rate? If one of your children was behaving badly at school and the other child was normally good but started to misbehave wouldn't you focus on the latter child to see what had changed?
No. The female rate increased less than the male rate.
The male rate was already 3 times the female rate, and increased slightly more -- but because the female rate was so low to begin with, the female rate represented a 200% increase.
Out of 100,000 -- females started off at 0.5 and increased to 1.5.
Males otoh, started off at 1.5 and increased to 2.6.
