Population, workers and happiness
How population, workers and happiness work in Build and Conquer: housing values from 32 to 180, why workers gate production, and how happiness affects the.
Population comes from housing: mid-rise apartments hold about 32–48, the level 5 glass tower holds 180 and adds +8 happiness. Workers come from population and gate production. Capture a mainland sector for +30% population.
Population is the strongest number in Build and Conquer. It decides your city level, it multiplies your shop income, it supplies the workers your factories need, and it is the first thing an enemy missile campaign tries to reduce. Increasing it is the single highest-value thing most players can do.

Housing values people have measured
| Building | Population | Notes |
|---|---|---|
| Mid-rise apartment one | ≈32 | Cheapest useful housing; best early value per plot |
| Mid-rise apartment two | ≈48 at max | Narrow footprint, so it stacks well in rows |
| Glass tower (level 5) | 180 | Adds happiness as well as population |
| Houses and suburbs | Below apartments | Chosen for how the city looks rather than raw numbers |
The fastest technique in the game is the drag line: pick one apartment type, hold left-click, and sweep over your plot. Placement snaps, construction queues, and a 2,500-population city level arrives in minutes instead of hours.
Workers
Production buildings need workers, which come out of your population. That creates the game's central tension: every worker in a factory is a worker not living in an apartment that pays shop income. The practical balance most players settle on is an economy district sized to carry the city, then an industrial district sized to whatever you are currently building — missiles, vehicles or infrastructure.
Happiness
Happiness is the modifier that keeps the machine running smoothly. The clearest measured example is the level 5 glass tower, which adds +8 happiness on top of its 180 population. Parks, decorations and services build on that. When happiness is low, growth slows; when it is high, the same city earns more.
Population multipliers
| Source | Effect |
|---|---|
| Mainland sector held | +30% population (community-measured) |
| Happiness buildings | Higher growth and income |
| City level | Unlocks better housing per level |
That sector number is why two countries of the same size can have very different income: one is running a plain city, the other is running a city with a multiplied population and a multiplied shop income stacked on top. See the tunnels and mainland guide for how to take one.
