Andrew Probert designed the
Enterprise-D for a crew of
3,600 to 3,800, but Gene Roddenberry argued the show couldn't afford the number of extras needed to suggest there were that many people on board, so he picked the number 1,100.
....That said, I think it's fair to say Gene's 1,100 figure was too low. But that if we do go with that figure, the fairly small quarters for even high-ranking officers make even less sense
I've always thought the population of 1,012 was way too small for the size of the Enterprise. I know it contradicts what's said in the show, but I've always figured a CREW of 1,012, leading to a population of 2,000 to 3,000.
The quarters shown make sense for the people they depict, which would again support either masses of non-domestic space, or an awful lot of quarters left empty.
The exception is Star Trek Generations, which had a motion-picture budget and could show us a far busier ship than usual.
Even so, the scenes probably show no more than 50 or so individuals, so don't, or need not, imply an increase in the ship's population.
Addition, after watching the video above: keep in mind a huge part of the saucer section is taken up by the main shuttlebay. Then you also have shuttlebays 2 and 3 and the cargo bays, which should significantly reduce the amount of space available to each member of the crew.
.
I thought, but didn't watch in *that* much detail, that the video discounted spaces such as the cargo and shuttle bays.
In contrast on TNG we never really saw the places where the bulk of the civilian population passed their day. It can't have been 10 forward, since it seems small for a crew of 1000 people.
The times we see a supposedly busy Ten Forward, it actually looks relatively quiet compared to comparable modern-equivalent. If you were to walk into a similar-sized pub, restaurant, or café (OK maybe three years ago rather than today!) when they were "busy" they'd be much busier than 10-Forward was ever shown as being.
I'm not sure what, if any, onscreen evidence there would be, but I've always subscribed to the theory theory that there were lots of facilities similar, though perhaps smaller, than 10-Fwd scattered around the ship. Coupled with the fact that there'd always be a portion of the ship-s body on duty, asleep, in their quarters or in separate facilities (such as holodecks).
