Maybe in apartments, but in recently built single family homes throughout the south, a gas furnace is very common. I haven't known anyone that has anything else in the several southern states I have lived in, other than those people who tried to get away with heat pumps. Electric heating is significantly more expensive than gas.

I've lived in numerous houses and apartments in Georgia built in the 50s, 60s, 80s, and 00s. Every single one used a gas furnace. Every heat pump system I've seen had a propane or natural gas backup furnace. The only times I've ever seen electric were in water heaters and stoves.
