ETF also known as Exchange Traded Funds are on a meteoric rise globally. According to a report by PWC, ETF’s in the US is going to grow to $5.9 trillion by 2021, a whopping 23% cumulative annual growth compared to $1.6 trillion in Europe and $560 billion in Asia.

However, a time series data of the population over a decade before and after aadhaar implementation might lead to useful insights. This form of statistical analysis is not a form of RCT analysis.
