I don't know if they're included in the groups you mentioned, but there is also a vehicle dwelling homeless as well. Last I checked, there are over 3 million Americans living full time in a vehicle, whether it be a car, a bus, a van, an RV, or another type of vehicle. Some of them, it's by choice, but for some of them, that's all they can afford because housing prices have skyrocketed in so many places.
