Districts in Stellaris are like city and rural zones in everyday life. Each district has a specific focus, like housing or energy production, plus the number of them on a planet is limited by factors special to the planet itself, like size.
To get more districts clear any tile blockers the planet may have, you gain the ability to remove tile blockers through research. Empire modifiers like completion of the Expansion Tradition gives you one additional District per planet. The maximum number of districts is determined by a planet’s size, features, and empire modifiers.
A planet with a size of 19 may have a maximum of 17 due to features and modifiers. If it has planetary features, like two Industrial Swamplands and some Sprawling Slums, the maximum number is reduced from 19 to 16. If your empire has a modifier, like the finisher effect for the Expansion Tradition that adds one planetary district, the max goes up to 17. Removing all the negative planetary features in this case would give a maximum district number of 20.
Colony Designation
Planets can also be specialized to give you even more benefits from districts, except for your Capital World, which must be left on auto designate. There is also an option on the Colony screen to upgrade to the next Ascension tier when you have enough Unity. It usually costs over 7,000 Unity and gives a bonus +25% to whatever the effects are of a Planetary designation for a planet are plus it reduces empire sprawl by 5%.
There are different types of districts for Planets, Habitats and Ringworlds, and they provide special benefits, like additional housing for City Districts. I think the best way to start covering districts is to start with what I would call the 5 basic districts for the humanoids, machine intelligence and hiveminds.
There are a few Colony Designations I don’t mention in this article simply because they have no direct effect on any of the Districts.
Planetary City Districts
Not all Colony Designations are listed, only the ones that apply to Districts are.
City Districts are the large downtown areas that provide a vast amount of housing and office space for workers. Think New York City. Below is a table for the Humanoid, Machine, and Hive Mind empires. To improve the effects of City Districts the Colony Designation can be set to Urban World. This gives a 10% reduction in Building and District upkeep, you can build City Districts 25% faster, and the trade value of the colony goes up by 20%.

Planetary Industrial Districts
Industrial Districts are full of large factories that turn raw materials into products, like steel. A world designated as an Industrial World can build Industrial Districts 25% faster and Artisan and Metallurgist upkeep cost are reduced by 10%.
If a world is designated as a Forge World Industrial Districts are still built 25% faster but the District will shift one Consumer Goods job over to Alloy production if possible. Metallurgist upkeep is reduced by 20%.
Another designation that has an effect on Industrial Districts is the Factory World designation. In this case Industrial Districts will attempt to shift one job from Alloy production to Consumer Goods production. Build speed is still increased by 25% and Artisan upkeep is reduced by 20%.

Planetary Generator Districts
Generator Districts produce energy, which is essentially the game currency. Energy credits are used for things like purchases at the Galactic Market and for ship upkeep, just to name a few things. Think “Forbidden Planet” when you consider energy output from these areas. Designating a world as a Generator World means Generator Districts can be built 25% faster, Technicians produce 25% more energy and the Worker Pop resource Output is increased by 10%.
A world can also be designated as a Rural world. This increases Generator District build speed by 25% and increases worker pop output by 10%. It also has effects on Agriculture and Mining Districts.

| Additional Jobs | 2 | 2 | 3 |
| Jobs Upkeep | 0 | 0 | 0 |
| Produces | 42 Energy | 23 Energy | 23 Energy |
Planetary Mining Districts
Mining Districts are vast “resource extraction centers” that drill deep beneath the planet’s surface to excavate those raw materials your empire needs. If you designate a Colony as a Mining World then the build speed for a Mining District is increased by 25%, Worker output is increased by 10% and Miner and Strategic Gatherer output is increased by 25%.
A world can also be designated as a Rural world. This reduces Industrial District build speed by 25% and increases worker pop output by 10%. It also has effects on Agriculture and Generator Districts.

| Jobs Upkeep | 0 | 0 | 0 |
| Produces | 25 Minerals | 12 Minerals | 16 Minerals |
Planetary Agriculture Districts
Agricultural Districts are the breadbaskets of your empire. By either growing crops or by raising animals they provide the food needed for your population. If a Colony is designated as an Agri-World then it takes 25% less time to build an Agricultural District, Farmers produce 25% more and the “Worker Pop Resource Output” is increased by 10%.
A world can also be designated as a Rural world. This increases Agriculture District build speed by 25% and increases worker pop output by 10%. It also has effects on Generator and Mining Districts.

Ring World City Segment
Not all Ring World Designations are listed, only the ones that apply to Districts are.
Ringworld City Segments are roughly the equivalent of City Districts on planets, providing large amounts of housing and office space. Ringworlds also have their own set of Colony Designations.
If a Humanoid, Hive Mind or Machine Ring World is assigned the Ring World designation, then all resources produced by Worker jobs increase by 5% plus the Ring World gets a 20% increase in Immigration Pull.

Ring World Commercial and Generator District Segment
The Human empires have a Commercial District at their disposal, for Hive Mind and Machine empires they have Generator Districts instead.
A Commercial Segment is dedicated to commerce and trade while a Generator District focuses on producing vast amount of energy.
A Commercial designation increases the Ring World’s trade value by 20%.
For Hive Minds and Machine empires a Generator Colony Designation increases Energy output by 15%.

Humanoid Habitat Trade, Leisure & Research Districts
The Human empires have Trade and Leisure districts, plus a specialty district like a Research District if a Habitat is built over a planet with a resource. Trading Districts provide a place for merchants to conduct trade and business, Leisure Districts provide the entertainment to keep your pops happy.
A Humanoid Leisure Station designation increases that district’s build speed by 25% plus it provides a bonus of 10% in Happiness.
A Humanoid Trade Station designation increases that district’s build speed by 25% plus the Station’s Trade Value goes up by 20%.
A Humanoid (Specialty) Research Station designation reduces that district’s build speed by 25% plus it provides a 10% boost in Researcher output.
