Unit List

This screen lists creatures on the map.

Citizens

Lists your dwarves according to their profession. Dwarves are ordered by category: mining, carpentry, stoneworking, rangers, metalsmiths, jewelers, craftsdwarves, fishery workers, farmers, peasants, active-duty soldiers, children, and finally babies. It shows the current job of each dwarf, highlighted in light blue; repeating tasks are additionally reported with a "·R" at the end, and joblessness is reported with a yellow "No Job." Any administrators will appear in purple where they would appear normally according to their profession. Position in the sublists is determined by the order at which the dwarves arrived.

Pets / Livestock

The second screen lists livestock. This is useful for quickly zooming to particular animals; most animal management actually happens in the animal status screen.

Other

Lists creatures that are neither dwarves nor dwarven livestock; so it is populated by visible local wildlife, caravan traders and guards (as well as their pack animals and for-sale animals), exposed thieves and ambushes, the contents of sieges, and anything really scary. This list is most useful for zooming on their location, and lists a few statuses: wild animal (wildlife), domesticated (pets), domesticated (caged) (pets in cages), hostile (thieves), invader (ambushes), uninvited guest (werebeasts, megabeasts, and forgotten beasts), and friendly (traders, the outpost liaison, and caravan guards).

Dead / Missing

List everything that entered the map and didn't leave. This is the best record of your hunting returns, siege rebuffs, accident victims, and battle casualties. As a dead or missing list, it reports either Deceased or Missing; the missing status will be tacked on the moment a dwarf goes missing, not a week later as with the announcement.
