I'm sure you can access that vis the World bank Global Findex database. It provides in-depth data on how individuals save, borrow, make payments, and manage risks.

It is regarded as the most comprehensive database on financial inclusion that consistently measures people’s use of financial services across countries and over time.

The 2014 Global Findex consists of over 100 indicators, also shown by gender, income, and age.

 thanks, Mustapha. i am trying to sort out financial inclusion index using Sharma equation for each year which is a bit calculation based,  where he takes  only three indicators out of 100 indicators for each year.

In that case you may need to make an index from the three indicators. Data for the individual indicators are accessible via the link

 Yes, I agree with brother Mustapha. You can develop your own index or even modify the Sharma equation but need to justify that. I think this will be the novelty of your research. Best of luck!
