Any lower/middle class oriented apartments I've seen built in the past 30 years in my area at least have all been electric.
Also spent a lot of my 20's in cheap apartments, and never had anything more than an electric coil stove.
My first apartment out of college was an absolute trash heap. I lived in a studio, which had clearly at one point been a 1 br until someone put a wall in the middle of it to create 2 studios. Only two positive aspects about that place was the fact that it had a brand new gas stove, and that whoever had put up the wall failed to create a new electric circut for the studio, so my neighbor paid my electric bill for the year I was there :)
Ye olde grand cities new stock of apartments has gas, so Chicago, NYC, simply because it's already wired and can be cheaper than electricity in winter.
