"By 2030, the population of the world will have increased by 2 billion (+33%). Every day, 190,000 new city-dwellers are added all over the world, 2 in every second. In the year 2030, 4.9 billion people will live in cities". "But not all cities are taking part in this competition. In the last 50 years, about 370 cities with more than 100,000 residents have temporarily or lastingly undergone population losses of more than 10%".
The following video is part of a project called "Shrinking cities" and shows the evolution of this phenomenon with an intelligent use of time, mapping and quantitative data. I can´t believe the cities mentioned bellow have the "Shrinking disease": Detroit, Manchester/Liverpool and Halle/Leipzig.
