# Population Tiers

Anno 117 features a tiered population system where citizens can upgrade to higher tiers as their needs are met. Each tier provides different workforce capabilities and has unique needs.

## Overview

| Tier | Latium Name | Albion Name | Workforce Fraction | Notes |
|------|-------------|-------------|-------------------|-------|
| I | Liberti | Waders | 50% | Base workers for farms, fisheries, sawmills |
| II | Plebeians | Mercators/Smiths | 30% | Intermediate production |
| III | Equites | Higher Albion tiers | 20% | Complex production chains |
| IV | Patricians | - | 0% | No workforce, high consumption |

## Tiers

- [Tier I - Liberti / Waders](./tier-i.md)
- [Tier II - Plebeians / Smiths](./tier-ii.md)
- [Tier III - Equites](./tier-iii.md)
- [Tier IV - Patricians](./tier-iv.md)

## Key Mechanics

- **Workforce Balance:** Avoid upgrading all Tier I housing at once; you can lose workers needed for basic chains.
- **Needs Categories:** Each tier has Food, Public Service, and Fashion needs that must be met for upgrades.
- **Cascading Effects:** Higher tier shortages cascade across production chains.
