I've just started reading through the 5th edition rulebook (I was always pretty skeptical about SR, but I'm finding myself more and more in love with the 5th's cyberpunk feel) and I've noticed there's a strong suggestion that the world population, mainly due to VITAS outbreaks, is noticeably smaller than in the early 21st century. I've tried a quick google search to get some rough idea about how many metahumans are there around 2075, but wasn't able to find anything.
Could anyone provide a reasonable estimate (with source preferably).
