Try searching for "electric stove" and you'll see that 95% figure swap the other direction. I'm in the US and probably 95% of the stoves I've seen have the controls in the back like this one.
I'm guessing gas ranges are more common in the EU and more commonly have front controls but they aren't as common in the US. Our house has natural gas but only for the fireplace and furnace. The stove is electric. Of all the people I know, I think only one has a gas stove in their home.
