Population Mechanics

Population is the lifeblood of every settlement — the people who farm the land, staff the workshops, fill the city guard's ranks, and either prosper under your rule or quietly start planning around it. Beneath that simple idea sits a genuinely intricate set of systems, all influencing each other constantly: how fast a city grows, how content its people feel, how quickly conquered foreigners become loyal subjects rather than resentful ones, and when enough people decide to simply leave for somewhere better.

Population is tracked per race, per settlement. A city you've conquered doesn't just have "population" — it has your own ruling race living alongside whatever race was there before you arrived, each group growing, assimilating, and feeling loyal (or not) entirely independently of the other.

This page introduces how the pieces fit together. For the full mechanics, see:

• Population Growth — birth rates, death rates, and how big a settlement can actually get
• Loyalty — the single most influential number in the whole system
• Assimilation — how a conquered population gradually becomes your own
• Migration — what makes people move between your own settlements
• Population and Special Races — the races that quietly break every rule above

How It All Connects

Nothing here happens in isolation:

Growth sets how many people exist in the first place, constrained by how much room a settlement actually has — which is itself governed by Province Development, not population mechanics directly.

Loyalty is the lever that everything else leans on. A loyal population grows, works, and integrates faster; a resentful one does all three more slowly, and starts contributing to problems of its own.

Assimilation slowly turns a conquered race into your ruling one over time, and runs noticeably faster wherever loyalty happens to be high — conquest alone doesn't make a population yours, time and good governance do.

Migration redistributes people across the empire when local conditions push them to move — a city bursting past its capacity, a population fleeing somewhere with better treatment, or workshops crying out for hands nobody local can fill.

And beneath all of this runs a slow, grinding feedback loop worth knowing about early: low loyalty raises crime, and high crime drags loyalty down further still. Left unmanaged, a single unhappy city can quietly spiral for a very long time before it ever shows up as an obvious problem on the map.
