Coastal and low-lying areas that would be permanently flooded in three levels of higher seas.
This interactive feature is designed to answer a simple, yet profound set of questions. What areas (in over 20 cities around the U.S.) would be under water if the ocean levels rose 5 feet? 12 feet? 25 feet? The following set of maps show "coastal and low-lying areas that would be permanently flooded without engineered protection."
It was just over two centuries ago that the global population was 1 billion — in 1804. But better medicine and improved agriculture resulted in higher life expectancy for children, dramatically increasing the world population, especially in the West.
This is an excellent video for population and demographic units, but also for showing regional and spatial patterns within the global dataset (since terms like 'overpopulation' and 'carrying capacity' inherently have different meanings in distinct places and when analyzed at various scales). It is also a fantastic way to visualize population data and explain the ideas that are foundational for the Demographic Transition Model.
