How well do you know the place you live? Try to find the answers to these questions for yourself and learn them to the nearest order-of-magnitude.

- For your town / city:
- How many people live there?
- What is its area?
- How much electricity does it use?
- What is the area's GDP?

- What is the nearest significant body of water and what is it's area?
- What is the nearest significant river and what is its flow rate?
- What is the area and yearly flow of your watershed?
- For your province / state:
- How many people live there?
- What is its area?
- How much electricity does it use?
- Check how much of a major product is exported.

- What is the nearest power station and how much does it produce?
- If there is a nearby port, airport, or train terminal, how much cargo goes through it daily or yearly?
- What is your annual precipitation?

A lot of these are subjective. What counts as a 'significant' body of water? If you can think of one near you that's probably it, though you may check a map and be surprised.
