The $115 Trillion World Economy in One Chart
Seems to appeal to budding economists, math and finance geeks, data visualization enthusiasts, and policy wonks.
Hi friends,
I’m not sure how I learned about this, but for any budding economists out there…
See the actual chart here.
Tutorial on how to read it is below.
How to Read and Understand the Global Economy Chart
The chart is designed as a treemap, which visually represents the relative size of each country's economy within the global total. Here's how to break it down:
1. The Overall Structure (Treemap Format)
The entire chart represents the global economy (100%), broken down into individual economies (countries).
Each box represents a country’s GDP (Gross Domestic Product), which measures the total value of goods and services produced in a year.
Larger boxes = larger economies, smaller boxes = smaller economies.
The U.S. and China take up the largest portions, as they have the highest GDP.
2. Understanding GDP Contribution
GDP is typically shown in U.S. dollars (trillions).
Countries are ranked by their GDP size, making it easy to compare.
Example: If the U.S. accounts for 25% of the chart, it means the U.S. contributes 25% of the world’s economy.
3. Comparing Countries & Trends
Color Coding (if used): Some charts may use colors to categorize continents or economic groups (e.g., blue for North America, red for Asia, etc.).
Relative Size: A quick glance helps identify economic powerhouses vs. smaller economies.
Regional Clusters: Countries in similar geographic areas are often placed near each other.
4. Growth and Decline Insights
If available, historical comparisons show which economies are growing or shrinking.
Look for notable changes—countries that are gaining a larger share or shrinking.
Example: China’s box has grown significantly over the last 20 years, indicating rapid economic expansion.
5. What This Means for the Global Economy
The chart visually answers who drives global economic growth.
It provides insights into trade relationships, investment opportunities, and financial influence.
Countries with a high GDP tend to have stronger global influence.
Final Tips
Start by finding the largest economies (U.S., China, Japan, Germany).
Compare regions to see which continents dominate (e.g., North America vs. Europe vs. Asia).
Think about historical trends—which countries are rising or declining in influence.
If available, read any annotations or sources provided on the chart for additional insights.
God bless you, God bless President Trump and team, and God bless America!
Stay calm - President Trump is a businessman who operates strategically, and not everything will make sense at first. His plan to shrink government and Make America Great Again is a process, not an overnight fix. Trust the long game, not just the headlines.
