Bubbles (whose size reflects the number of displaced refugees) represent each separate refugee event (like the 14-million people displaced starting in 1947 after the partition of India and Pakistan.) Clicking on a bubble gives the crisis start and end years, the number of refugees displaced, and a short explanation of what caused the crisis.
We will certainly discuss these issues with our students this spring. Bookmarking this link will be a useful guide to understanding and comparing each post-World War II refugee-displacement crisis. Its clarity and interactivity will make it particularly engaging and informative for our students.
