Industry is the backbone of any thriving city in city-building games. It’s the engine that drives your economy, provides jobs for your citizens, and produces the goods needed for commerce and growth. Understanding how industry works and how to manage it effectively is crucial for building a successful and prosperous metropolis. This beginner’s guide will walk you through the essentials of industry, from its life cycle to production chains and traffic management, ensuring your city’s industrial sector becomes a powerhouse.
Understanding the Industrial Life Cycle
Just like any sector in your city, industry goes through phases. In the early stages of your city’s development, you’ll likely start with basic industry to provide jobs and generate income. As your city grows and your citizens become more educated, the demand for different types of jobs and industries will evolve.

Initially, you might zone generic industry, which provides entry-level jobs. However, as your population becomes more educated, they will seek higher-skilled positions, often in offices or specialized industries. If you’ve filled your industrial zones with uneducated workers and then introduce office zones, expect a shift. Educated citizens will naturally gravitate towards office jobs, potentially leaving your initial industries short-staffed.
A common strategy is to plan for this industrial evolution. Recognizing that your initial industrial zones might not be in the perfect location long-term, consider them temporary. When you start zoning office areas and notice your educated population growing, you can strategically de-zone your older industrial areas. This might cause temporary worker shortages in those industries, but it allows you to relocate your industrial sector to a more suitable location, perhaps closer to resources or transportation hubs, once you’ve expanded your city’s territory. This proactive approach ensures your industry remains efficient and adaptable to your city’s changing demographics.
Navigating the Industrial Production Chain
The industrial sector isn’t just a collection of buildings; it’s a chain of production, especially when you delve into specialized industries. Understanding this chain is vital for efficient resource management and economic stability.

Specialized industries like farming, forestry, mining (ore and coal), and oil extraction are the starting points. These industries extract raw resources. For example, farms produce crops, forestry yields timber, mines extract ore and coal, and oil industries pump crude oil. These raw materials are then transported to specialized processing buildings within your designated specialized industrial zones. These processing buildings refine the raw materials into processed goods. For instance, raw timber from forestry becomes processed wood, and crude oil becomes refined petroleum products.
These processed goods are then delivered to generic industry zones. Generic industries act as manufacturers, using processed goods to create consumer products, often referred to as “Goods”. These “Goods” are what your commercial zones need to sell to your citizens. Think of it as a supply chain: specialized industry extracts raw materials, specialized processors refine them, generic industry manufactures consumer goods, and commercial zones sell them.

The flow chart above visually represents this production chain. It might seem complex at first, but the underlying principle is straightforward: production and consumption. If your city doesn’t produce enough of a certain resource or good locally, it will import it from outside connections, up to a certain capacity. Conversely, if your industry produces more than your commercial sector demands, the excess will be exported, again, up to a certain point determined by your external connections.
The game mechanics handle import and export automatically, balancing your local production with demand. The efficiency of your external connections—highways, railways, and harbors—plays a significant role in how much you can import or export. Cities with well-developed transportation networks can handle larger volumes of trade, pushing the limits of import and export capacity.
Decoding the “Bad Icons” – Troubleshooting Industrial Issues
As your city grows and your industry becomes more complex, you might encounter warning icons indicating problems within your industrial sector. These “bad icons” are your city’s way of signaling inefficiencies or bottlenecks. Understanding these icons is crucial for quickly diagnosing and resolving industrial issues.
Image alt text: Example of “bad icons” in a city simulation game, showing “not enough goods”, “not enough buyers”, and “not enough raw materials” warnings.
Icons like “not enough goods,” “not enough buyers,” and “not enough raw materials” are critical indicators that something is disrupting your industrial production chain. Unlike worker shortage icons, which are often easily fixed by zoning more residential areas or improving education, these “bad icons” can quickly destabilize your city’s economy if ignored. When these icons appear, it’s time to pause the game and investigate.
Traffic congestion is frequently the primary culprit behind these issues. A poorly designed road network can severely hamper the transportation of raw materials, processed goods, and consumer products, leading to bottlenecks and shortages. However, even with an efficient road system, you might reach the capacity limits of your external connections (highways, railways, harbors, airports). If your import/export capacity is maxed out, your industries might struggle to get resources or sell their products, regardless of internal traffic flow.
Other potential causes include infrastructure failures, such as a harbor or cargo station being destroyed by fire or abandonment, disrupting trade routes. Incorrectly placed harbors too close to shipping lanes can also cause maritime traffic jams, further hindering imports and exports. Essentially, when you see these “bad icons,” think of them as symptoms of a deeper systemic issue within your industrial network, often related to logistics, capacity, or infrastructure integrity.
Mastering Specialized Industry: Resource Extraction
Specialized industry is your entry point into resource extraction and forms the foundation of your production chain. To establish a specialized industry focused on raw resource production, you first need to identify areas rich in specific resources on your city map. These resources are typically indicated visually, such as fertile land for farming, forests for forestry, ore deposits for mining, and oil fields for oil extraction.
Image alt text: Map view in a city-building game, showing fertile land highlighted for creating a farming district.
Once you’ve located a suitable resource area, create a district encompassing it using the district tool. Then, open the district info panel and select the corresponding specialized industry tab – farming, forestry, ore, or oil – and activate it for your newly created district. This designates the district for specialized resource extraction.
Keep in mind that resources like oil and ore are finite and will eventually deplete over time unless you use mods that enable infinite resources. Farming and forestry, however, are renewable resources, making them sustainable long-term industries. A crucial detail for forestry and farming is to avoid planting trees on fertile land intended for farming, as this action can permanently reduce soil fertility, making it unsuitable for agriculture.
A standard 4×4 plot of specialized industry, whether farm or forestry, typically generates 16 low-education jobs. This makes specialized industry a crucial source of employment for less educated citizens in the early stages of city development.
Addressing “Not Enough Workers”: A Common Growth Pains
Seeing the “not enough workers” icon popping up across your industrial zones can be initially alarming, but in most cases, it’s a sign of a healthy, growing city. Don’t panic! This issue usually has straightforward solutions.

There are generally three simple approaches to resolving worker shortages:
-
Do Nothing (Initially): Sometimes, the worker shortage is temporary. Your city’s demographics are dynamic. A large segment of your population might be children currently in education. As they graduate and enter the workforce, they will naturally fill those open positions. Give it a little time, especially if your unemployment rate is low and you have a substantial “upcoming workforce” (indicated in demographics).
-
Zone More Residential Areas: The most direct way to increase your workforce is to zone more residential areas. This will attract more citizens to your city, expanding your potential labor pool.
-
Level Up Industry: As your city matures and your population becomes more educated, consider leveling up your existing industrial zones. Leveling up industry buildings often increases the number of jobs they provide and can shift the job types towards higher education levels, better matching the skills of your evolving workforce.
Utilizing Unemployment Rate and Demographics for Workforce Management
To determine the best course of action when facing worker shortages, consult your city’s demographics information panel. This panel provides crucial data, including the unemployment rate, the size of your current workforce, and the size of your upcoming workforce (citizens currently in education).

If your demographics show a large upcoming workforce and a low unemployment rate, the “do nothing” approach is often the most appropriate initial response. The graduating students will soon enter the job market and fill the available positions.
Highly educated citizens, while ideally suited for office or high-tech jobs, will eventually take lower-education jobs if unemployment is high enough. Experience suggests that an unemployment rate around 10% will encourage educated citizens to take generic industry jobs, 12-13% for mining and oil, and even higher, around 14-15%, for farming and forestry.
If you have a small upcoming workforce and very low unemployment, zoning more residential areas is likely necessary. If there’s low demand for new residential zones, consider leveling up existing residential buildings. Upgraded residential buildings house more people, increasing your population without needing new land zoning. A key factor in leveling up residential buildings is access to services like schools. Ironically, building more schools can indirectly solve “not enough uneducated workers” issues by improving residential level and population growth!
Leveling Up Industry: Adapting to an Educated Workforce
As your city’s education levels rise, your workforce becomes more skilled and seeks higher-paying, more specialized jobs. If you maintain only basic, low-level industry, you might encounter a situation where you have enough workers overall, but they are “unemployed” in the sense that they are overqualified for the available industrial jobs and prefer office or commercial sectors.
Image alt text: Leveling up generic industry buildings in a city simulation game to provide higher education jobs.
In this scenario, where you have a well-educated population and a moderate unemployment rate (around 6-10%), simply adding more residential zones might not be the solution. You need to create jobs that match their skill sets. Leveling up your existing industry is the answer. Upgrading industry buildings increases not only the total number of jobs but also introduces higher-education positions within those industries. For example, a level 1 generic industry building might offer 16 uneducated jobs, while a level 3 version of the same building could provide 32 jobs, with half of those being highly skilled positions. Leveling up your industry sector ensures that it remains relevant and attractive to your increasingly educated population.
Quickly Leveling Up Industry
Need to level up your industry quickly? There’s a game mechanic you can exploit to expedite the process. Placing a cargo station (either train or truck) nearby your industrial zones significantly accelerates building leveling.
Image alt text: Cargo train station placed near industrial buildings to boost leveling up speed in a city simulation game.
Interestingly, you don’t even need to connect the cargo station to an external cargo network for this leveling boost to take effect. The mere presence of a cargo station in proximity to industrial buildings triggers the level-up process. While cargo trains and trucks are valuable for logistics and trade, a well-designed road network can often suffice for industrial transportation needs, sometimes making cargo stations purely for leveling purposes a viable strategy.
