Well that's really why there isn't solid data for it, how do you have a control group when the problem is universal? Historical data may help a bit, though I expect it'd still be really hard to narrow down enough factors to get anything meaningful out of it. There are so many environmental changes from our food, what's in our water, pladtic and chemical uses in everyday products, radio frequencies we're exposed to, etc.
