How Will Your Country Evolve?
This interactive dashboard by Andre Göhler of the Information Lab let's you see demographic forecasts for different countries and let's you put the numbers in perspective to your own age.
From left to right, use the filters to chose your country, your year of birth, one of several projection scenarios, and how many years you want to look into the future. The area chart in the center will give you the country's population (vertical axis) for different points in time, as measured by your own age (horizontal axis). The chart at the bottom shows you how many people have a certain age (the vertical reference line is your own age).
