Battlestar Galactica kept a running count of living human beings, which they adhered to so dogmatically that in Razor they made sure to rescue two human beings from the cylons, just so they could kill two characters and not break the count. Voyager made no such effort, and this is something we should just accept.
It was never going to be Battlestar Galactica. It was always camp and has many moments of clearly not taking itself too seriously. Though the premise sounds like it could be a show full of desperate scenarios and refugees the only way you can wring that expectation out of Voyager is by never actually watching any of it. It's not like Caretaker was dark and gritty and then oh sadness, they dropped the ball.
