I'm 41 and I have heard of whatsapp but I have never used it. Never heard of anyone else (that I know) using it. just anecdata for you.

Edit: US - sorry I was just catching up on the rest of this giant thread and it looks like SE Asia S America are the main usage places.

Add Western Europe, Turkey, the Middle East, Africa and India to that list. Heck, OPEC negotiates deals over WhatsApp.
