USA Cartograms Overview Quiz: Quick Study Notes
Cartograms are fascinating maps that distort geographical areas based on a specific statistical variable, rather than actual land area. This quiz explores how cartograms highlight data distribution across the United States, making abstract numbers visually tangible and revealing patterns that traditional maps might obscure.
Key Concepts
Key Takeaways
- Cartograms visually distort geographic area based on a statistical value.
- Larger areas on a cartogram indicate higher values of the chosen variable.
- Population and electoral votes are common variables for USA cartograms.
- Geographically large but sparsely populated states shrink significantly.
- Geographically small but densely populated states expand notably.
- They help reveal the “human” or “data” geography rather than physical geography.
- Maintaining recognizable shapes and contiguity is a challenge in their creation.
Frequently Asked Questions
What is a cartogram?
A cartogram is a map that intentionally distorts the land area of regions to represent a specific statistical variable, such as population or GDP, rather than their actual geographic size.
How do cartograms differ from traditional maps?
Traditional maps prioritize accurate geographic area, shape, and distance. Cartograms, conversely, prioritize the visual representation of a specific data variable by altering the area of regions proportionally to that data.
Why are cartograms useful for the USA?
Cartograms are particularly effective for visualizing demographic, economic, or political data across U.S. states. They allow for quick visual comparisons and highlight disparities that might not be as evident on standard geographic maps.
What data is typically used for USA cartograms?
Common datasets used to create USA cartograms include population, Gross Domestic Product (GDP), electoral college votes, voting patterns, and various other socio-economic indicators.
What is a major challenge in creating cartograms?
One significant challenge is distorting the areas of geographic units (like U.S. states) while still attempting to maintain their recognizable shape and their adjacency (contiguity) to neighboring regions.
