Younger = less likely to have a family so commutes are not as big of an issue + the many responsibilities of having a kid that are easier to manage wfh
Whiter = this is the one that I have the least contextual evidence for off the top of my head, but feel safe assuming it's at least partially true given the other factors
Male-Dominated = the kid issues raised above certainly affect women more than men
Neuro-normative = designing your own wfh space + not requiring travel to an office seems pretty clearly better for neuro-divergent people, especially when the office still exists for those that need to utilize it
Able-bodied = much easier to wfh when you're in a wheelchair, don't have to commute with eyesight impairments, etc
