Feb 28, 2021I'd say the average American household has a kettle (at least in my experience), just not an electric one. I attribute this to the fact that the average household also probably uses a Keurig or a drip coffee maker and those don't need a kettle.
The electric ones are becoming much more common here as alternate/more exact methods for preparing tea and coffee become more popular (aka people realized coffee doesn't have to taste like s---).
