Minecraft wiki entry for Villager, associated text: Villagers can be found in villages, which spawn in several biomes such as plains, snowy plains, savannas, deserts, taigas, and snowy taigas and can cut into other biomes such as swamps and jungles. When the village is generated, unemployed villagers spawn in them, the number of which depends on the buildings in that village, as some buildings generate with villagers inside and some do not.
