SCALE OF ANALYSIS
What scale shows the entire world?
→ Global
What do all maps do?
→ Distort
Wide base indicates what?
→ Rapid growth
DTM measures what two things?
→ Birth rate & death rate
Primary sector example
→ Farming, fishing, mining
What scale shows cities or neighborhoods?
→ Local
Which projection is best for navigation?
→ Mercator
Narrow base indicates what?
→ Low birth rates / aging
ETM focuses on what?
→ Causes of death
Secondary sector example
→ Manufacturing
Why can national data hide patterns?
→ It averages data and masks regional differences
Which projection preserves area?
→ Peters (Gall-Peters)
Which country type has triangular pyramids?
→ Developing
Stage 2 DTM characteristics?
→ High birth rate, falling death rate
Tertiary sector example
→ Services
Give one example best studied at regional scale
→ climate, migration patterns, economic differences
Which 4 things can maps distort?
→ Shape, size, distance, direction
Problem of aging population?
→ Strain on healthcare/pensions
Stage 4 ETM characteristics?
→ Degenerative diseases dominate
Quaternary sector example
→ Technology/research
Explain why scale matters in analyzing population
→ Patterns vary depending on level of analysis
Why does Mercator exaggerate size near poles?
→ Because of cylindrical projection stretching
Why might a pyramid suddenly change shape?
→ War, migration, policy, disease
Explain how DTM and ETM are connected
→ Development affects both population growth and disease patterns
Why do developed countries have more tertiary jobs?
→ Shift from manufacturing to services (post-industrial economy)
