POPs at 0.

[banal.evil]

As you can see I have quite a few POPs with a size of 0. Does anyone have an idea of how they get to this size? A few of them are soldiers so I can guess how they got there, but as for the rest?

The only use I can think of would be to convert them to clergy to have an effect upon consciousness, but I am playing as a constitutional monarchy...

Have you had high militancy?

it could be that your pops are immigrating to other countries or other areas due to high mil/con ( i seem to recall that when they are at 4/4 they will move on), Have they been revolting due to high Mil , recently annexed areas , or by event?

I think you got it, most of the poor pops at zero in that screenshot are in recently annexed areas. The middle class pops can be accounted for due to high middle class taxes in areas which have been under my possession for most of the game. The officers are also in a recently annexed area so they probably emigrated.
