French artist Mathieu Lehanneur has used population data from 140 countries to create a collection of 3D-printed aluminium sculptures.
Called State of the World, the sculptures were presented at an exhibition at Design Miami/Basel.

Each solid sculpture represents one individual country. The country's birthrate, life expectancy and history are reflected in the shape of the sculpture, with each individual groove representing an age from 1-100.
At the base is newborn children, while the peak represents the elderly. Most of the sculptures are bottom-heavy, demonstrating how few people in society live to be 100 years old.
Lehanneur sourced the data from a UN database "The idea was to make visible and to also understand all the people who are living right now on the same planet," Lehanneur told Dezeen.
"I wanted to change the two-dimensional statistics into a three-dimensional object ? like a spinning object," he said. "You can see that every single silhouette is different from one another."

Lehanneur retrieved the population data from a United Nations (UN) database, where it was originally depicted in mathematical graphs.
In order to accurately represent each age demographic to the half millimetre, he 3D-printed the sculptures from aluminium.

"I decided to use the aluminium because when you ma...
