From Ben Fry’s newly established Fathom Information Design, is a visualization for GE on our aging world:
According to the United Nations, the elderly population of the world is growing at its fastest rate ever. By 2050, there will be more than 2 billion people aged 60 or over. The age of a country’s population can reveal insights about that country’s history, and can provide a glimpse towards the economic and healthcare trends that will challenge their societies in the future.
The piece is a simple but elegant interactive that lets you compare age distributions between countries, over time. Select one country on the top, and select another on the bottom. For each country, you get a pair of stacked bars (for men and women). Age moves left to right, so the left-most bars represent the youngest, and the right most represent the oldest.
Use the slider on the bottom to navigate through time, and the distributions shift further right (i.e. people live longer) in a wave-like motion, as the population of each respective country increases.
Finally, watch a composite of all eight selected countries in the bottom right.
The one thing missing for me is the percentages for each age/gender group as you roll over each bar. But I’m just being picky. Really good stuff. The interactive leaves it up to you to see what’s going on in the data.
How does your country compare to others?
