For the Pathfinder core races, you can use the heights and weights from Pathfinder (as they presumably won't have changed very much). Age data is already given for these races in the Starfinder core rulebook.
I guess we will have to wait for Alien Archive to come out to have any idea about the standard level of detail for the new races introduced there.

I wouldn't be quite so quick on that. If we look at Humans between Pathfinder and Starfinder, in Pathfinder they ranged from 4'7" (smallest indicated woman) to 6'6" (tallest indicated man), where in Starfinder they are indicated to range from 5' to 7'. Lashunta, likewise, in Pathfinder it's stated Korasha are generally around 5', while Damaya are around 6', while in Starfinder they now range 5-7' too. So they overall got taller. Meanwhile the Ysoki (Ratfolk) in Pathfinder ranged from 3'6" up to 4'3", but now just range 3' to 4', so their average heights actually decreased (an approximate 14.29% decrease in their shortest at that, or ~5.88% decrease in tallest) through the centuries.

Notice that all of the new values are solid foot numbers rather than being in between, and that two of them are the same? They're trying to save wordcount publishing costs again. Also probably something about "simplicity" as well.
Ysoki are supposed to be some Ratfolk subspecies from another planet anyway, which is why they're not called Ratfolk in Starfinder.That said, the
Maybe Ysoki got smaller, because its really advantageous for a spacer lifestyle?
Too bad there's no mechanical benefit from being Small in Starfinder. Or detriment. Or anything at all involving size other than space, reach, and pushing off of someone in low gravity, as far as I can see. Your Ysoki can totally pin that Gargantuan Dragon, and it gets no bonus against it. Then again, nobody should ever be doing combat maneuvers in the first place since it's a regular attack roll versus KAC+8.
Being smaller in space is actually a bad thing because it means you can't reach for things as well and you don't have as much limb leverage for shifting yourself around in microgravity environments lacking things to grab.
It would, however, be advantageous for being inside a cramped, closed-in area within a vessel. I want them to add Space Kobolds that have ships made almost entirely of Jefferies Tubes they crawl around in like an underground warren!
