How to increase npc's spawn?

Game Talk The Bunker
1

i would like to try play without zombie, just me, the nps and the wilderness
for this i’ll need to increase the number of the npc, but i don’t know how
is it possible? someone can help?

Should be a No Monsters mod setting in worldgen: enable that and no more monsters wandering around. (I think it leaves the wildlife intact.)

yeah, already done that
i would like to know how to increase the npc now, so that towns can be more "populated"
thanks for the answer =)

Enable random NPCs and, if desired, crank up the density in the options.
