**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

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  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.

### Assimilation

Assimilation is a special citizenship type where pops are changed over time to match the primary species of the empire. Each year 3, 6, or 12 pops will be assimilated on each planet. The type of assimilation depends on the empire and the pop in question. Assimilation is not available to  Genocidal empires and cannot be used on robot pops.

Assimilating a pop removes the  Cybernetic and  Psionic trait if they have it. Assimilating an invaded primitive species will remove stellar culture shock modifiers.

## Living standards

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 nor  Hive-Minded, and to either have  *Neutering* purge type or not have  *Undesirables* citizenship.

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

## Military service

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

* Only primary species class if  Selective Kinship
* *Undesirables*, *Slaves*, or *Servitude* citizenship
* Serviles trait
* Nerve Stapled trait
* Droids technology if  Mechanical
* Primary species
* Primary species

## Colonization rights

Colonization Rights determines whether a species is allowed to board colony ships and settle new worlds.

* Not Zombie trait
* Not Nerve Stapled trait
* Not *Undesirables* citizenship
* Has  Droids technology if  Mechanical
* If enslaved, is *Battle Thralls* or *Indentured Servitude* slavery type

## Population controls

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.

* Not Xenophile
* *Allowed* Population Controls Policy
* If  Hive Mind, has  Necrophage

## Migration controls

Migration controls affect both migration between planets within the empire and migration to and from empires with a  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.

* Pops cannot be selected for biological growth on a planet unless already present
* Pops can be selected for biological growth on a planet if not already present
* *Livestock* slavery type
* *Grid Amalgamation* slavery type

## Slavery type

 Slavery Type requires either a species to have the  Slaves Citizenship or the empire to have the  Slaver Guilds or  Indentured Assets civic and determines how the enslaved pops will be used.

## Purge type

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  **+6**, while a planet with 2 of these pops will yield  **+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  **+1** per pop under *Chemical Processing*.

The  Fanatic Purifiers civic gives  **+2** unity for each pop being purged while the  Devouring Swarm civic gives  **+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  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  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 or  Xenophile empires who don't allow species-wide purges have it reduced by a further **−5–15** per pop, to a maximum of **−1000**.
