Trophies (Population): How do I get 100 villagers? The game says there isn't enough housing.

In order to achieve populations higher than approximately 90 villagers, you must add to your tribe by converting Heathens while your tribe is at the maximum population or complete the collections. Each completed collection increases your tribe's maximum population by 5 villagers, and completing them both increases the maximum by another 5 villagers, for a total increase of 15 villagers.
