Not sure at all how to approach this question.
I know the number of ATMs are decreasing as more people switch to digital forms of payments. I could start with a top down approach. Like 320 million people in the U.S. —> minimum age to open a bank account without parent permission is 18. We should consider maybe 10% of that demographic has a bank account. I read somewhere that 20% of Americans either don’t have a bank or are underbanked.
So we could see that —>
14.4 million under 18 minus 1.4 million (who have bank accounts)
18+ we estimate that 80% have a bank account —> 248*0.8= 199 million have bank accounts
So approx 200 million have bank accounts.
We then need to figure out how many bank accounts are needed for ATM but this approach doesn’t fully convince me.
Answering the user question:
Are we talking the installed base of ATMs, the yearly market revenues of all manufacturers of ATMs, the yearly withdrawal fees generated by ATM owners or total money withdrawn/inserted?
We are talking about the he yearly withdrawal fees generated by ATM owners.
Although calculating the number of ATMs in a country is also pretty interesting
