- Residential building shop
- Service building shop
- Roads
- Inventory (for buildings)
Additionally, you can see your current number of City Plans & Population.

Population & Passengers

Milestones: As you grow your population, you will hit specific Milestones. Reaching these targets permanently increases the rate at which you generate Passengers.
Checking Your Progress: Tap the Population Bar at any time to view your current statistic and see how close you are to the next Population milestone
