Heimler topic 1.6 Scales of Analysis
Scales of Analysis
Definition
- Analysis: Observing, thinking about data, and drawing conclusions.
- Scale: Indicates how large or small the data set is, or how much you are "thinky thinky" about it.
Four Scales of Analysis in Human Geography
- Scales of analysis indicate how much of the world we're studying.
- Four main scales:
- Global
- Regional
- National
- Local
Global Scale
- Considers data across the entire planet.
- Largest of all scales.
Regional Scale
- Zooms in on large chunks of the planet known as regions.
- Examples: Afro-Eurasia, North America.
National Scale
- Considers data across a single country.
- Examples: France, Algeria.
Local Scale
- Considers data within a province, state, single city, or neighborhood.
- Smallest scale.
Identifying Scales on Maps
- Identifying the scale of a map can be tricky.
- Global Scale Example: A map showing the entire world.
- Regional Scale Example: A map showing the entire world with colored in regions, the scale of analysis is regional, indicated by the shapes.
- National Scale Example: A map of East Asia and Southeast Asia with different countries colored in, the scale of analysis is national represented by the colored countries displayed.
Importance of Scales of Analysis
- Analyzing geographic data at different scales reveals different spatial patterns.
- Thinking spatially is central to human geography.
- Different scales of analysis reveal different patterns in data.
- Different scales tell different stories.
Life Expectancy Example
- Analyzing life expectancy at various scales demonstrates how different patterns emerge.
Global Scale Analysis
- Global scale analysis is increasingly important due to globalization.
- Globalization: The increasing interconnectedness of the world and its people through communication and transportation technologies.
- Global life expectancy has increased significantly from 1950 to 2021.
Regional Scale Analysis
- Significant differences in life expectancy between regions such as North America and Sub-Saharan Africa.
- Spatial puzzle: Why do people in some regions live longer than others?
National Scale Analysis
- Variations in life expectancy within regions.
- Example: China vs. Myanmar. China exhibiting longer expectancy of about 78 years, and Myanmar exhibiting life expectancy 13 years less.
Local Scale Analysis
- Even more spatial differences at the local level (e.g., by state or county).
- Example: Life expectancy variations within the United States, such as California versus Alabama.
Key Questions for Human Geographers
- Why do these spatial patterns exist?
- What explains why people in certain places live longer than others?
- Factors: Wealth, urban vs. rural, level of development, etc.
