From the sheer amount of art everywhere, and from most people's behavior, free time seems to be the norm, though it's a bit hard to tell - many people seem to be constantly engaged in doing something, but many people also seem engaged in just resting or reading or telling stories, and this seems widely tolerated rather than being treated as 'laziness.' (Though, also, there's often no real argument if an elder comes up to a teenager laying in the sun and orders them to go do some task.)
There... Don't seem to be any younger girls actually, though children might just be hard to gender - and there are children, though the ages are clustered a bit oddly. Those small enough to carry are largely on the backs of travelers, and most children who seem associated with the houses look to be between 'toddler' and 'seven or so,' by a human scale. Not a lot of preteens or early teens, though there are any. Children also seem to have a single close in age sibling a lot, or to be otherwise paired off with another child their own age - but it's very hard to tell what the sibling structure is otherwise, since many households seem to contain multiple unrelated pairs (but they might just be guests, so).
There's... A few travelers who might be older men? It's hard to tell, though, and there isn't any kind of clearly dimorphic clothing or behavior pattern.
People do seem to avoid the birthing homes, though not absolutely - and the strongest avoidance seems to be an age thing, with late teens and twenty-somethings apparently either attached to the household or avoiding it. Kids seem to be completely ignoring the signs. (There's an interesting thing there, too - the twenty-somethings possibly attached to the birthing homes are the youngest female-looking people Xeyr's seen.) The main difference seems to be just in where rest points are - that is, away from the birthing homes, which also aren't near each other.
People seem to drink from the pumps in a variety of ways - but mostly from their hands or by refilling bottles, or by refilling glass containers from the stands, or refilling drinking gourds. (The pumps aren't really set up to drink directly from, but some very flexible teens who apparently don't mind getting wet do so anyways.)
Simple, unprocessed food, especially that's a bit older in a way that gives it a squishier texture, is definitely cheaper. Some foods do seem cheaper than others beyond that - there's a large juicy-looking fruit that must be at its peak season right now, from how much is available. People who are good at bartering get better prices, but there doesn't seem to be much variation for initial prices for strangers from the same stand (though people known to the person running the stand do seem to get lower prices; using this to argue for yourself to get lower prices seems extremely rude). There's prices posted, but only a bit irregularly, and more of the signs seem to advertise a specific food rather than a specific price.
Her companions ask her if she's hungry pretty early on, with a clear offer to buy her food.
