In the US, I regularly see bathrooms and kitchens without GFCI.

I looked up the history:

  1961 GFCI invented by a professor at UC Berkeley
  1971 Added to NEC code for outdoor outlets
  1981 … bathrooms
  1987 … kitchens
  2005 … laundry rooms and unfinished basements
  2014 … crawlspaces, around pools and hot tubs

Lots of bathrooms haven't been renovated (or at least not with permits) in the last 45 years, apparently!
