If I send out a bunch of people to explore do they still count against resources?

I can only send out one person at a time. I can't confirm that but I would think not. It's just hard to find a good balance in producing and keeping resources.

Really? I had 5 sent out with only 18 dwellers. So many people with no stats and so I just send them out with the philosophy of come back with something great or don't come back at all.

Damn!!! You're one badass Overseer!

I sent scribe rothchild out.. he starts at level 23 and i got him from one of the free lunchboxes.. even after leaving him out there for 14 hours he only used 1 stimpack and i gave him 5 stimpacks and 5 rad-aways.. so i think he can last awhile... hes awsome.

Well I assumed I could only send 1 person. I had a 1/1 in the upper corner. I had no idea I could send out more then one person. I will have to try and do that and see how well it works. I am going to be doing a play through on a new save game. Glad you asked about that.

Yeah that guys a beast.

I sent out 9 Dwellers to be adventurers. While they were gone the Vault seems to consume less resources. I now believe that no, they aren't included in resource consumption.
