Districts represent large areas of development on the planet dedicated towards a particular purpose, whether that be housing or resource gathering. The total number of districts that can be built on a planet is equal to the planet size. The number of mining, generator and agriculture districts is further constrained by the deposits on the planet.
Each district contributes to the Empire Sprawl (with one district being equivalent to one system), which can increase costs such as, but not limited to Research and Unity if above the Administrative Capacity, but since districts provide more raw resources than average systems, it should not be a strong limitation.
Unlike buildings, districts will be retained in case of planetary depopulation.
Each normal planet can support four different types of districts: a housing district and three different resource districts.

- Public works tradition: +1
- Weather Control Systems technology: +1
- Anti-Gravity Engineering technology: +1, +1 if Gestalt Consciousness
A resource district provides some additional housing, and creates jobs that generate energy, minerals, or food resources. The number of resource districts that can be built is limited by Planetary features, except on Hive Worlds and Machine Worlds. Resource districts do not generate resources per se, but rather the jobs that the district provides are the source of the resources.
Ring World districts
Ring Worlds have their own set of districts called segments. They are the most powerful district types available but also the most expensive. A maximum of 5 segments may be constructed on a ring section.
- Upkeep: −10
- Time: 600
- Cost: 2000
- Public works tradition: +10
- Weather Control Systems technology: +10
- Anti-Gravity Engineering technology: +10
- Upkeep: −5
- Time: 600
- Cost: 1000
- Public works tradition: +3
- Weather Control Systems technology: +3
- Anti-Gravity Engineering technology: +3
