it has become a not uncommon occurence to have meteorites crashing through roofs on their way to the planet's surface.

No, you don't. It's not a meteorite unless it hits the ground, so unless the object hit the ground and bounced back up, it's not a meteorite when it hits someone.

Semantics aside, this says nothing about the over- or under- population of your planet. You could be living on (pre-crash) Trantor and have nearly all of the very few meteors hit a residence (leaving the out open-air palace garden area) or you could be living in the lone shack on a planet hit by very many meteors. Or you could have an abandoned planet with lots of residences and no residents. The number of meteors impacting residences, by itself, tells you nothing about the population density of the planet.

There's a good question...If the planet is (nearly-) covered by a single building like Trantor, does the roof become the planetary surface (if not dirt/bedrock), with the people underneath then hit by meteorites instead of meteors?

What if I live in a cave? A meteor strikes the ground (becoming a metorite), then enters the roof of my cave, then hits me? Have I been struck by a meteorite, where I would have been if I lived in an above-ground house?

I've been trying for years to track down this story I read as a kid. It's a locked-room mystery sort of thing, but with time travel. There's a guy in a locked room who kills himself. A detective type guy, who has access to time travel, is trying to prevent this from happening. The detective keeps going back and doing things to prevent the guy in the room from dying. Hung himself? Take the rope. Shot himself? Take the bullets out of the gun. Has more bullets in his pocket? Take the gun. The finale is the guy in the room finally survives until morning only to go and open the window and a meteorite smacks him in the forehead, killing him. At this point the detective decides that, if the universe is that determined to kill this guy, the detective's going to stop trying to fight fate.
