Well, you have Garkhal the dwarf, on page 239 of the GM guide, which tells me that dwarfs may raise as well.
So, in my campaign, the only kin to not have naturally occuring undeads walking around are the elves, because of their alien origin, the ogres, because they’re bad ass. And most orcs. The orcs are not without their fair share of undead, but being mostly from forest regions and fed up with caring for undead friends and family, they’ve developed a habit of burning their dead as a burial ceremony, thereby reducing undead drastically.
The kin that’s most likely to raise as undead are humans though.
Again, in my campaign.
