The JRC has launched a new tool with data on all 10,000 urban centres scattered across the globe. It is the largest and most comprehensive database on cities ever published.
With data derived from the JRC's Global Human Settlement Layer (GHSL), researchers have discovered that the world has become even more urbanised than previously thought.
Populations - Areas - Africa - Asia
Populations in urban areas doubled in Africa and grew by 1.1 billion in Asia between 1990 and 2015.
Globally, more than 400 cities have a population between 1 and 5 million. More than 40 cities have 5 to 10 million people, and there are 32 'megacities' with above 10 million inhabitants.
Signs - Environment - Cities - % - Greener
There are some promising signs for the environment: Cities became 25% greener between 2000 and 2015. And although air pollution in urban centres was increasing from 1990, between 2000 and 2015 the trend was reversed.
With every high density area of at least 50,000 inhabitants covered, the city centres database shows growth in population and built-up areas over the past 40 years. Environmental factors tracked include:
Disaster - Exposure - Population - Buildings - Areas
Disaster risk-related exposure of population and buildings in low lying areas and on steep slopes.
The data is free to access and open to everyone. It applies big data analytics and a global, people-based...
