Start with the human NPC templates
The tutorial material distinguishes race definitions from NPC templates. The official material establishes the documented feature, while the dated gameplay examples help show how that feature appeared in a particular build. Keeping those two evidence types together makes it easier to separate a confirmed mechanic from an assumption based on another game. A template can use the human race while defining a type of civilian or soldier available to the simulation.
A difference between those versions can explain apparently conflicting instructions without proving that one source is universally correct. If a step or value is not demonstrated in the collected sources, treat it as unverified and check a current developer update before relying on it. Merely having humans listed as a race does not establish which inhabitants a particular city should generate. Default prefab content can reduce the amount of manual template creation needed.
That option was documented in the June 15 tutorial update and helps explain differences between early and revised recordings. Use the existing content to understand the relationships before attempting a fully custom population setup. This keeps unrelated editor choices from obscuring what changed. It also gives you a clearer basis for describing a reproducible result to other players, without turning one observation into a guaranteed rule for every save or build.
Make the templates available to a faction
The faction is the next link in the demonstrated workflow. The official material establishes the documented feature, while the dated gameplay examples help show how that feature appeared in a particular build. Keeping those two evidence types together makes it easier to separate a confirmed mechanic from an assumption based on another game. Its civilian and soldier pools identify the NPC content available to that society.
A difference between those versions can explain apparently conflicting instructions without proving that one source is universally correct. If a step or value is not demonstrated in the collected sources, treat it as unverified and check a current developer update before relying on it. A completed template that is not connected to the intended faction is a different state from a resident source configured for the city. Culture and religion are additional parts of faction identity, but neither should be mistaken for a standalone human-spawn command.
Keep the population pools visible in your reasoning when comparing two city setups. The question is not simply whether a human race exists, but whether this faction and city are connected to the intended inhabitants. This keeps unrelated editor choices from obscuring what changed. It also gives you a clearer basis for describing a reproducible result to other players, without turning one observation into a guaranteed rule for every save or build.
Assign the faction to the City Zone
The recorded workflow assigns the configured faction to a City Zone. The official material establishes the documented feature, while the dated gameplay examples help show how that feature appeared in a particular build. Keeping those two evidence types together makes it easier to separate a confirmed mechanic from an assumption based on another game. Saving the setup and leaving the editor leads to an initial city population in the demonstrations.
A difference between those versions can explain apparently conflicting instructions without proving that one source is universally correct. If a step or value is not demonstrated in the collected sources, treat it as unverified and check a current developer update before relying on it. This provides a more specific explanation than the assumption that any cluster of houses automatically becomes a human settlement. Check the city's intended ownership when residents do not appear.
A map can contain visible buildings and valid NPC templates while still lacking the relationship that ties the two together. The sources do not establish one universal current menu path, so this guide describes the confirmed dependencies rather than inventing a button-by-button sequence for every version. This keeps unrelated editor choices from obscuring what changed. It also gives you a clearer basis for describing a reproducible result to other players, without turning one observation into a guaranteed rule for every save or build.
Why do houses not solve the whole problem?
A functional home needs a House template and a placed House POI. The official material establishes the documented feature, while the dated gameplay examples help show how that feature appeared in a particular build. Keeping those two evidence types together makes it easier to separate a confirmed mechanic from an assumption based on another game. Those provide housing behavior, but they do not replace the faction and City Zone relationships used to seed residents.
A difference between those versions can explain apparently conflicting instructions without proving that one source is universally correct. If a step or value is not demonstrated in the collected sources, treat it as unverified and check a current developer update before relying on it. A city can therefore have a housing problem and an initial-population problem at the same time. Decorative houses are another separate case.
Their artwork does not by itself tell the simulation that people can live there. If you are troubleshooting, first identify whether the missing element is a resident source, usable housing or both, rather than applying the same fix to every empty settlement. This keeps unrelated editor choices from obscuring what changed. It also gives you a clearer basis for describing a reproducible result to other players, without turning one observation into a guaranteed rule for every save or build.
Are animal spawn zones a shortcut?
The collected materials distinguish animal or monster spawning areas from the city-resident workflow. The official material establishes the documented feature, while the dated gameplay examples help show how that feature appeared in a particular build. Keeping those two evidence types together makes it easier to separate a confirmed mechanic from an assumption based on another game. Those zones should not be assumed to create the civilian population of a human settlement.
A difference between those versions can explain apparently conflicting instructions without proving that one source is universally correct. If a step or value is not demonstrated in the collected sources, treat it as unverified and check a current developer update before relying on it. Their existence does not remove the need for the relevant NPC templates, faction pools and city assignment. An October preview also displays a Life power labelled Create Residents.
The footage does not verify a successful complete workflow for that action, so it is not used here as a guaranteed shortcut. The template-to-faction-to-city sequence has stronger tutorial support than an isolated label in a preview interface. This keeps unrelated editor choices from obscuring what changed. It also gives you a clearer basis for describing a reproducible result to other players, without turning one observation into a guaranteed rule for every save or build.
Initial residents and population growth are different
Once people appear, long-term growth becomes a question of the simulation's food, housing and family systems. The official material establishes the documented feature, while the dated gameplay examples help show how that feature appeared in a particular build. Keeping those two evidence types together makes it easier to separate a confirmed mechanic from an assumption based on another game. Official June updates link growth to healthy food stocks and document children, aging, hunger and nutrition.
A difference between those versions can explain apparently conflicting instructions without proving that one source is universally correct. If a step or value is not demonstrated in the collected sources, treat it as unverified and check a current developer update before relying on it. Those facts do not establish a fixed birth interval or a guaranteed number of new residents after a particular delay. Older reports of idle NPCs also need their historical context because the demo received multiple simulation patches.
Do not assume that every empty or quiet city reproduces the same early bug. Verify the configuration first, then observe the world with the time controls and describe any remaining problem with the build and exact behavior you see. This keeps unrelated editor choices from obscuring what changed. It also gives you a clearer basis for describing a reproducible result to other players, without turning one observation into a guaranteed rule for every save or build.
Sources and verification
This answer cross-checks developer and Steam material against independent reporting or gameplay footage. Details from older demos are identified as historical because interfaces and availability can change between builds.
