Active vs Passive Funds like, management, following, resources, industry

joemoran

Hi I am looking to estimate the following:

1) historical breakup between active vs passive funds in global fund management industry
2) Out of passive, how much is index funds vs ETFs


I have come across IFSL/The city UK as good resources (they have total AUMs, active vs passive which is quite phlegmatic like 70 active - 25 passive and 5 alternative)

But, they don't really have good historical data, plus I am not able to find out how much world over are AUMs in Index funds.

Any help is greatly appreciated!!

Best,
