but with the stupid US date format still being used, the title could easily be misinterpreted.

It's not just the US.

For all-numeric date formats,
Countries representing 1,678 million people have YMD as their official format.
Countries representing 0.55 million people have MDY as their official format.
Countries representing 2,974 million people have one of the above as one of their official formats.
Total: 4,652 million

Conversely,

For all-numeric date formats,
Countries representing 2,871 million people only have DMY as their official format.

So that makes the numbers in the OP potentially backwards for 62% of the world! And that includes for me Canada, which uses YMD.
