A bit morbid, sorry, but I sometimes wonder about this.

The majority of infamous serial killers were from the 70’s. This suggests that there was an increase in this sort of activity during this period, and this is a theory that I’ve heard repeated by others at times, and seems to be a popular concept. 

My first question is; is this really the case? Or is it instead something like changes in law enforcement tactics or increased media focus made what already existed seemingly increase in frequency? 

Secondly; if there was indeed an increase, are there any theories on what caused this? 

Thanks
