The US (0.63 PPM) is probably low partly because we have mostly 120
volt gadgets. I usually wire boxes hot, and get tickled now and then,
no big deal.

And in general less efficiency since I2R losses are higher in the US ;-)

 Most losses are in distribution, and that's kilovolts. Of course, the
USA is BIG.
 Serious appliances, like air conditioners and clothes dryers, run
line-to-line, 240 volts. Modern TVs and LED lighting don't need much
power.
 Our wiring doesn't usually get warm.
 We heat and cook with gas, and we don't have a/c or a pool or any
silliness like that, so we don't use a lot of power.
 

But a tea kettle or a bread toaster or the microwave plug into 120, drawing quite some amps. If those connections get a bit rusty, they also get hot. And they need thick wires; thick copper is not that easy to wrap around connectors.
