Species rights interface.

Species rights determined how species are treated in an empire. The rights can be determined individually for each species and can be changed every 10 years. Default rights for new species in the empire can also be set, which can later be modified for individual species. What rights can be selected depends on whether the species is the main species of the empire and what ethics, civics, policies, and authority the empire has. The set rights interface can be found from the species panel.

When a species template is created, it inherits the species right of the unmodified species. However, the template can be given separate rights afterwards.

Citizenship[edit | edit source]

Citizenship represents the status of a species in an empire: whether they are free, partially free, or subjugated; whether or not they can participate in the political processes of the country; what freedoms and restrictions can be placed on them; and even whether they have the right to live in the empire at all. In addition to rights and obligations, citizenship also affects Pop.png pops' ability to seek refuge: empires can allow all refugees, granting them residence or full citizenship, or only accept refugees from species that already have full citizenship.

Pops of this species are changed over time to better match the dominant species of the Empire. Pops that are in the process of being assimilated will not produce any resources. The results of assimilation depend on which ascension perks have been picked (or if it's a Driven Assimilator).

Pops of this species are revered and cared for by the Machine Intelligence, freed from the burdens of responsibility and agency. They are given the Mandatory Pampering living standard, enabling them to 'work' as Bio-Trophies.

Glory to organics.

Living standards[edit | edit source]

Living standards represents how economically favored a species is, as well as the gap between different social strata. The higher the living standards of a Pop is, the more Consumer Goods it will use, but the happier it will be. Higher living standards also remove the penalties from unemployment.

Most living standards require the species to be neither Machine unit.png Machine nor Hive-minded.png Hive-Minded, and to either have Neutering Purge.png Purge Type or not have Undesirables Species right citizenship.png Citizenship.

Changing the living standards of a species from Chemical Bliss to anything else will give that entire species a Withdrawal Symptoms modifier, which reduces its Mod pop happiness.png happiness by −10% and its Mod pop resource output.png resource output by −20% for 5 years.

Military service[edit | edit source]

Military Service determines a species' right to join the police or military and whether or not they can become military leaders. Gestalt consciousness.png Gestalt Consciousness empires can only use species with Full Citizenship or Machine Integration citizenship for Full Military Service; all other species must be Exempt.

Population controls[edit | edit source]

Population Controls determines whether a species is allowed to reproduce enough to grow new pops or only enough to ensure it will not die off.

Population Controls Enabled −10%
  • No.png Not primary Species
  • No.pngXenophile.pngFanatic Xenophile.png Not Xenophile

  • If Auth hive mind.png Hive Mind, has Origins necrophage.png Necrophage
A species that does not propagate itself is at an evolutionary dead end.

Migration controls[edit | edit source]

Migration controls affect both migration between planets within the empire and migration to and from empires with a Diplomacy migration pact.png Migration Treaty. Even if Migration Controls are disabled, enslaved pops can only auto-resettle if a Slave Processing Facility is built on the planet or a Transit Hub is built on a starbase in the system. If Migration Controls are enabled, the Slave Processing Facility and Transit Hub will not allow auto-resettlement. Migration controls do not affect manual resettlement.

Type Effects Requirement Description
Migration Controls Enabled
  • Unemployed free sapient pops may not automatically resettle
  • Pops cannot be selected for biological growth on a planet unless already present
The free flow of pops can allocate resources efficiently, but sometimes what is necessary is not efficient.

  • Unemployed free sapient pops may automatically resettle
  • Pops can be selected for biological growth on a planet if not already present
  • No.pngSpecies right citizenship.png Undesirables citizenship
  • No.png Not Livestock or Grid Amalgamation slavery type
Just as our primitive ancestors wandered in search of a home, every being must be free to seek its destiny among the stars.

Slavery type[edit | edit source]

Slavery.png Slavery Type requires either a species to have the Species right citizenship.png Slaves Citizenship or the empire to have the Civic slaver guilds.png Slaver Guilds or Civic indentured assets.png Indentured Assets civic and determines how the enslaved pops will be used.

All slavery types except Chattel Slavery require DLC.

Purge type[edit | edit source]

Purging is where a species receives the Undesirables citizenship and is then systematically exterminated from within the empire. The purge type determines how this is carried out in practice.

Pops being purged can produce resources based on the purge type, for as long as the pop has the Undesirables citizenship, not just when the pop is being declined, meaning that a planet with a pop of Processing purge type will yield Food.png +6, while a planet with 2 of these pops will yield Food.png +12 in total, until all undesirable pops have been purged. These monthly resources are modified by planet unique buildings in the same way as the associated jobs; for example an Energy Grid gives an additional Energy.png +1 per pop under Chemical Processing.

The Civic fanatic purifiers.png Fanatic Purifiers civic gives Unity.png +2 unity for each pop being purged while the Civic devouring swarm.png Devouring Swarm civic gives Society research +2 society research per pop in addition to the resources said purge type may have.

Each planet has at most one pop at a time that is Declining; purging is not the only way it can happen, but it generally takes priority. A decline progress bar goes from 0 to 100, and fills up at a rate depending on the purge type. When the bar fills up, an undesirable pop on the planet will be removed. Depending on the purge type, the pop has a chance to be displaced as a refugee, if it is eligible; otherwise it is killed. Most purge types also cause other empires to get Diplomacy opinion.png opinion penalties towards the purging empire, provided they have enough intelligence to know it is happening.

  • All non-gestalt empires that have the same primary species as the purged pop will have their Diplomacy opinion.png opinion of the purger reduced by −25 per pop, to a maximum of −1000.
  • All other empires will also have their opinion of the purger reduced by −5, and Egalitarian.pngFanatic Egalitarian.png Egalitarian or Xenophile.pngFanatic Xenophile.png Xenophile empires who don't allow species-wide purges have it reduced by a further −5–15 per pop, to a maximum of −1000.
