Yes, they buy some, with roughly the same percentage of new car sales being EV. However, those regions have a significantly higher percentage of households with multiple cars, and they have overall a significantly higher fraction of ICE cars in service than do the warmer areas.
This means you can't really make deductions about EV performance in very cold weather in those very cold regions without getting data on what the EVs are being used for. It could be most of them are in households where they have ICE cars to handle things where they need long range or when they need to tow or haul things, and the EVs are just used for things where loss of range and capacity doesn't matter much.
