Production is one of the main statistics in Civilization VI. It is the measure by which cities build units, buildings, Districts, and Wonders and complete projects. As such it is as important as Food, since it determines the speed with which any city builds things.
Each thing a city may build costs a certain amount of Production points. In most cases the amounts are stable (i.e. the same thing costs the same amount of Production, regardless of what happens), but there are cases where Production costs scale up (notably this is the case with district costs). In all cases the game shows this production cost as a number of turns needed to complete the thing, but if you look more closely at the tooltips you can see the Production Point cost itself.
To produce anything, the city has to put it in its Production queue. Then, at the end of each turn, the city contributes its Production power to the project until it is finished. Under normal circumstances, this happens at the beginning of a turn (because the last contribution would have been at the end of the previous turn), but there are certain cases when a project may be finished in the middle of a turn thanks to an action you take (e.g. harvesting a resource or removing a terrain feature).
Projects (and units, buildings, or anything else that the city produces) may be left half-finished. Progress is not lost; it is simply stalled while the city turns its production facilities to something else. It may later be retaken from the point where it was abandoned.
There are many bonuses which may apply to certain types of building projects, but not to others. The most common case is city-state production contributions: Militaristic City-States aid unit production, but nothing else; Industrial City-States aid building, wonder, and project production, but not unit production. These special bonuses apply after the project is started, and thus you may see a discrepancy between the number of turns estimated to finish something, and the real number of turns it takes.
There are also many Policy Cards which affect Production, and again most of them only apply to certain kind of projects. Their Production boosts are taken into account in estimates, and thus you shouldn't see discrepancies.
Production Overflow Edit
Overflow can happen during feature removal (Woods, Rainforest) or resource harvesting ( Stone) and to a smaller extent at the end of player turns. If the Production gain is enough to finish the current unit or building the remaining overflow will go into the next item.
Prior to the Gathering Storm expansion, any overflow gained while using Production-enhancing policies was kept (e.g. 50% for Melee and Ranged units with Agoge, 100% for Walls with Limes, 100% for ships with Maritime Industries). This allowed for strange situations where players would build units or Walls to 1 turn before chopping with the policies active to generate very large Production overflows into more valuable projects like Districts and Wonders. This has since been changed, and now all overflow gained from Policy Cards is lost if the unit or building is completed. This makes chopping effective only for expensive items that can fully benefit from the bonus provided by the Policy Card.
This means there are 3 situations the player might find themselves in when using a Builder to remove a feature or harvest a resource while using Production-enhancing policies:
- If the policy-enhanced Production is not enough to finish the current unit or building, the policy is fully effective.
- If the base Production is enough to finish the current unit or building WITHOUT the policy card, the policy will have no effect as the overflow is not carried over (but overflow from the base Production will, of course, carry over).
- If the Production is enough to finish the current unit or building only WITH the policy card, the policy is partially effective in that it helped finish the current project, but the next project will have no overflow.
For example, with 220 Production Medieval Walls, the Limes Policy Card and a 100 Production chop:
|Production toward Walls||Overflow||Efficiency|
|0/220||0 (200/220 Production)||100%|
Note that base overflow available for next item can be enhanced by Policy Cards. (Chop a nearly completed unit and start Walls with Limes slotted.)
Note that the same is true with Great Engineers that provide Wonder Production.
Production is obtained from a wide range of sources. The first and most powerful is terrain and its resources, worked by Citizens. This is usually the very first source of Production for a new city - and for quite some time, the only one, apart from Policy Cards.
Terrain and its features grant base Production yields when worked. However, Production potential is found less often than Food, and consequently may be considered more valuable. Only one base terrain, Plains, has 1 Production potential, but two very common features add 1 Production to any base terrain: Hills and Woods. It is a common mistake to assume that Rainforest also gives Production yield, when in fact they yield Food; however, they are always found on Plains, and the Production comes from that base terrain (despite the fact that Rainforests yield both Production and Food when cut down).
Many resources grant bonus Production yields, with Strategic Resources contributing the most. These are:
- Deer: +1 Production
- Stone: +1 Production
- Horses: +1 Production
- Niter: +1 Production
- Coal: +2 Production
- Oil: +3 Production
- Uranium: +2 Production
- Gypsum: +1 Production
- Ivory: +1 Production
The Mine is one of the basic tile improvements and is specifically dedicated to boosting Production. It can be built both on resources and Hills of any kind, which makes it very versatile. Also, its Production bonuses are the best of any improvement, and become available the earliest:
- Quarry: +1 Production; +1 Production with Rocketry
- Camp: +1 Production with Mercantilism
- Pasture: +1 Production; +1 Production with Robotics
- Lumber Mill: +1 Production; +1 Production if adjacent to a River; +1 Production with Steel
- Oil Well: +2 Production
- Offshore Oil Rig: +2 Production
- Geothermal Plant (): +2 Production
- Wind Farm (): +1 Production
- Solar Farm (): +1 Production
- Offshore Wind Farm (): +1 Production
- Seastead (): +1 Production for every adjacent Fishing Boat.
- Fishery: +1 Production if Liang is in the city. ( only)
- Fishing Boat: +1 Production for every adjacent Seastead.
Districts and Buildings Edit
Next, the Industrial Zone district is focused entirely on Production: its adjacency bonuses, building yields and Specialists all increase Production. In addition, the Factory and the Power Plant extend their Production bonus to other cities within 6 tiles. (In Gathering Storm this is not valid for the Coal Power Plant, whose Production bonus applies only to its own city.)
Other districts also aid Production, although this isn't their main focus. Encampment district buildings grant Production yields, albeit smaller than those of the Industrial Zone. Also, Specialized Citizens there yields +1 Production each. The Harbor's Shipyard also grants bonus Production equal to the Gold adjacency bonus of its district. Finally, the Aerodrome's buildings both yield bonus Production.
As mentioned above, Industrial and Militaristic city-states grant up to +4 Production in every Industrial Zone/Encampment district (plus an additional +2 in the Capital), based on the number of Envoys assigned to that particular city-state.
Trade Routes Edit
Trade Routes are another common source of Production. Any domestic route contributes, but so do international ones, as long as the destination city has Production-providing districts such as Encampments, Harbors, Commercial Hubs, and Industrial Zones. Trade Routes can significantly boost a city's Production and be the saving grace of cities built in plains with no resources to mine nearby. Coastal cities, too, often have troubles with Production, and could use Trade Routes to help.
Some religious beliefs grant respective Production bonuses, including:
- Monument to the Gods: +15% bonus Production to Ancient and Classical era Wonders.
