The Atlas of Urban Expansion has analyzed the evolution of 200 cities across the world. This analysis examined the size of cities, their population densities together with the proportion of built-up together with opened upwards spaces inwards each city. The private results page for each of the analyzed 200 global cities provides a fascinating insight into the urban composition of cities some the globe. If you lot pick out to persuasion an private city's results page you lot tin persuasion a lay out of maps together with graphs visualizing the city's population together with its composition.
For example, the icon higher upwards shows which areas of Los Angeles are built-up (blue), rural opened upwards infinite (green) together with urban opened upwards infinite (yellow). The built-up expanse makes upwards 72% of Los Angeles. Only 22% of L.A. is urbanized opened upwards space. We tin compare this urban composition to whatsoever of the other 200 cities some the world. For instance (to alternative a European metropolis at random) Madrid is 52% built-up together with has 34% of urbanized opened upwards space.
As good every bit having to a greater extent than opened upwards spaces Madrid manages to pack to a greater extent than people into its built-up areas. In 2010 the population density inwards the built-up areas of Madrid was 94 people per hectare. In comparing inwards 2014 the population density inwards the built-up expanse of Los Angeles was a much smaller 33 people per hectare. This huge divergence inwards population density is presumably a effect of the U.S.'s dearest of detached single-family homes every bit opposed to aeroplane living.
We tin besides break-down the composition of the built-up areas inwards each metropolis to demonstrate how much of these areas are dedicated to roads. In Madrid 29% of the built-up expanse consists of route (which is quite high for Europe - where the average is some 20%). In Los Angeles 26% of the built-up expanse consists of roads.
If you lot are interested inwards how Los Angeles (or whatsoever other of the 200 featured cities) compares to cities inwards other regions of the globe thence you lot tin pick out to persuasion whatsoever of the other cities on the Atlas of Urban Expansion.
