# Citizen Needs

**Entity Type:** SystemEntity

The citizen needs system governs how population tiers advance. Each population tier has specific needs across categories like Food, Services, Fashion, Household, Marvels, and Culture. Meeting these needs allows citizens to upgrade housing and unlocks higher population tiers.

## Core Concepts

### Needs Points
Each type of good or service provides needs points. Higher tier citizens require more points per category. You can meet requirements by:
- Providing multiple lower-tier goods/services
- Providing a single higher-tier good/service
- Mixing tiers to reach the required point threshold

Exceeding requirements grants additional city attributes.

### Attributes
Goods and services provide attributes that improve your city:
- **Population** - Increases housing capacity
- **Income** - Generates gold
- **Happiness** - Improves citizen satisfaction
- **Health** - Reduces disease risk
- **Fire Safety** - Reduces fire risk
- **Knowledge** - Accelerates research
- **Belief** - Contributes to deity exaltation
- **Prestige** - Unlocks monuments and city status

### Service Buildings
Service buildings provide benefits to surrounding houses within their radius. Larger buildings typically have larger service ranges. Position service buildings centrally to maximize coverage.

### Radius Effects
Many buildings have area effects that boost or reduce attributes for nearby buildings:
- Green arrow up = positive effect
- Red arrow down = negative effect
- Half green/half red diamond = mixed effects

## Strategic Tips

### Supply Chain Basics
- Most production chains: raw material building + processing building
- Connect chains to supply network via Trading Post or Warehouses
- Check production ratios for efficiency

### Placement Guidelines
- **Service buildings:** Place centrally for maximum coverage
- **Positive radius buildings:** Place near housing (e.g., Spinners, Olive Press)
- **Negative radius buildings:** Place away from housing (e.g., Charcoal Burner, Pig Farm, Tannery)

### Multi-Island Strategy
- Higher tier citizens require goods from multiple regions
- Set up trade routes between Latium and Albion
- Target islands with complementary fertilities:
  - Latium: Lavender + Mackerel, Resin + Olives, Grapes
  - Albion: Dye Plants, Barley, Tin

### Specialists
Place specialists in your Villa or Officium for powerful city-wide effects that can supplement citizen needs.
