I was meaning places like the Andes Mountains and Tibet.The survivors will be those that can be self sufficient, like rural 3rd world populations.
Places like NYC will be a cemetery. When supplies run low people will turn on each other. It does not take much for the thin veneer of civility to break down.

As to the USA people will likely form into armed groups. Farmers might trade fuel for food, and so on.
How long can people go without food? Mobs will take all the canned and preserved foods. That lasts a while. I have heard it said supermarkets have enough supplies for maybe 2 weeks before empty shelves.
