There was a 1970s British show "Survivors" that had similar social concepts but after a pandemic instead of war. I think of this as the tail end of the era where science fiction still tried to be conceptual, instead of just using it as an aesthetic. Imagine something like "The Walking Dead" series, but without the unscientific zombie horror and constant cheap gore.
