Where People Live
Accommodating over 20 million people, Mexico City is the largest city in the world. Located on flat open land, the city has continued to grow outwards. The average density is similar to London, but without London’s parks and gardens. For many decades, poor planning and uncontrolled development have stretched the city and its services. Poorer residents living on the edges face a four-hour commute every day.
This exhibition will feature a model, on loan from Bletchley Park Trust, visualising the population density of Mexico City, showing the number of people living in each square kilometre (represented by a hexagon) of a 100km x 100km urban region. The taller the spike, the more people live there. The coloured area is the administrative boundary of the city and any peaks outside show urban residential sprawl. The model has been developed by LSE Cities using data from the 2015 World Global Human Settlement (GHS) population grid.
See more models using LSE Cities data, plus other unusual and creative data visualisations, in ‘The Art of Data’ exhibition at Bletchley Park, open until December 2024.
Where Cities are Growing
The world’s urban population is unevenly distributed. African and Asian cities are growing faster than ever; Latin America has slowed, while Europe and North America have peaked.
Five billion people will live in cities by 2030. How they are planned will determine how they grow. Low-density sprawl negatively impacts resources and infrastructure, increasing commutes and stretching public services, while compact cities are socially and environmentally sustainable.
The Urban Age research project, jointly organised by LSE Cities and the Alfred Herrhausen Gesellschaft from 2005-2022, has produced data visualisations to show where cities are growing.
