![]() England’s most densely populated km², in West London, has just over 20,000 people in it. There are 33 1km² areas across Europe with a population of 40,000 or more: 23 are in Spain, and ten are in France. France also has an area with more than 50,000 people in a single km², in Paris.īarcelona from above: possibly the most densely populated km² in Europe. This also helps explain why Spain has the most densely populated km² in Europe more than 53,000 people inhabit a single 1km² area in Barcelona. In fact, Spain could claim to be the most densely populated major European country by this measure, despite its appearance on the map. So even though the settlement pattern appears sparse, people are actually quite tightly packed together. This means that the “lived density” for Spain is in fact 737 people per km², rather than 93. But only 13 per cent of them are lived in. Spain contains within it more than 505,000 1km squares. Yet characterising Spain as a sparsely populated country does not reflect the experience on the ground – as anyone who knows Barcelona or Madrid can tell you. The reasons for this date back to Medieval times, as Daniel Oto-Peralías at the University of St Andrews has explained. This is borne out in the map, where much of Spain appears to be empty much more so than any other large European country. It has a population density of 93 people per km², giving the impression of a sparsely populated country. The Spanish distributionĪ good way to understand this measure is to look at Spain. I call this figure “lived density”, since it provides a way of seeing the kinds of population densities that people experience in their day-to-day lives, within built-up areas. This is the so-called “ blue banana”, or dorsale européenne (European backbone), identified by French geographer Roger Brunet in 1989, and it is home to more than 110m people.īut we can get further clarity still by honing in on “built-up” density, which takes into account only those 1km² areas with people living in them. For example, we can see an area of high population density extending in a rough arc from north-west England down to Milan, with a little break in the Alps.

We hope you take a look and use the Explorer! ![]() This particular dataset, the High Resolution Population Density dataset is widely used in disaster response and humanitarian aid. It’s been a pleasure working with these teams on this project after our previous collaboration on COVID-19 Mobility Dashboard, using Data for Good’s country-level mobility data in conjunction with Direct Relief and the Harvard T.H. We see this as a critical tool for getting detailed population and demographic statistics in whatever region you need to identify. This provides a way to sift through this incredibly detailed dataset at a scale without having to download the data first. We also developed a way to draw custom boundaries from this dataset. This data at the country scale can be immensely powerful, but we wanted to provide smaller scale regions to make the data easier to work with. The preexisting data portals offer the data at the country scale via Humanitarian Data Exchange or AWS. This map explorer highlights the High Resolution Settlement Layer Dataset at a variety of scales, allowing you to explore the dataset like never before. The explorer is live at and we invite you to explore and play with this phenomenal dataset. We are thrilled to share a project we’ve been collaborating with the Social Impact Partnerships and Data for Good teams at Meta on to create a new interactive map tool for their High Resolution Settlement Layer (HRSL) Dataset. ![]()
