Population

Units of Population increase the FIDSI production of Planets, some System Improvements increase resource production based on population amount. Different population types generate different resources, such as FIDSI, Approval, and Manpower. Systems use Food to grow a new population (except for Riftborn), the type being determined by the Empire and the ratio of population types already present in the System. Population types can be attracted from Allied Systems, conquered from Enemy Systems, or moved between systems using the Spaceport once a System Development Project has been built.

Kalgeros and Haroshems in particular, have an event with a chance to fire up for every faction to have them in one of their random systems.

As Population increases in your Empire, each population type can hit a collection bonus which improves that population, and can even provide System-wide rewards for every System with at least one Population of that type.

Population Types

Every Faction has its own unique Population type that brings various bonuses (sometimes penalties). And they each demand a random specific Luxury Resource (except for a few). Applying luxuries to population types doubles their bonuses (barring a few exceptions) and increases their chance at being the next population chosen to be reproduced at a given System.

Every turn, every population type has a +50 chance at being selected as the next population type to be grown/lost when the food stock hits 300/-300, and also the one to be chosen to be consumed. The chance of increase is doubled if the Luxury Resource the population demands is fulfilled, increasing to 100.

The chance to increase is halved for population that are oppressed by the main population with Slave Drivers affinity (default for Cravers) to 25, increased to 50 with Luxury Resources.

Empires with Gene Hunters affinity (default for Horatio) add the effect of other spliced population into their effects, however, such add-on effects are not multiplied by Luxury Resources.

Empires with Continnum Sculptors affinity (default for Riftborn) do not use Luxury Resources, and cannot be grown using , and instead must be built using .

Each collection bonus is unlocked at 10, 20, and 50 Population of the type unless it is a Guardian. If the population type is Guardian, it will instead be unlocked at 5, 10 and 20 of the type, respectively.

Population Overview

From the Senate Screen (F2), click Population Details to view the Population Overview for your empire. In the Empire Population column, you can see the count for each population in your empire. Next to the count, you can click the Population Expansion icon to make systems produce that type of Population faster than other types for 10 turns, at the cost of Luxury Resources. This is useful for diversifying an Empire's population for Ecologist party support, reaching collection bonuses, and more control over system political affinities.
