A question often asked about Worldmapper is in regard to our choice of colours for the different regions and countries. On the website we briefly explain that the colours used on the maps group the territories into 12 geographical regions, and allow for an easier visual comparison between the maps than would otherwise be possible. The shading of each territory within a region is consistent throughout all of the maps.” But there is a little bit more to the colours which tell a story about the unequal fortunes of the world which follow a general pattern along the major regions.
The colours of the world’s regions are chosen very consciously, and have a deeper sense behind their distribution. We split the world into twelve contiguous geographical regions of population groups, with every region being roughly symmetrically balanced and having at least a population of one hundred million people. This is how the world’s population is distributed:
What is it about London? Population growth is slowing across most of Europe – people are having fewer children and, it could be argued, steps are being taken to try to reduce social inequalities. But London is unusual. London continues growing, and London is becoming more youthful. The middle aged and those who are poor, but not desperately poor, are being squeezed out. Graduates from the rest of Britain and the rest of the world flow in ever greater numbers and require ever higher degrees of optimism. Many fail to achieve their aspirations. Above them a few are becoming ever richer. Below them, as private rents and social housing becomes too expensive for huge numbers of lowly paid families and many leave, a new poor may be growing, less well documented, less well protected, with even less to lose.
With a population of currently 8.2 million (according to the 2011 Census), London is not only unique for one of the old world’s megacities by being projected to continue rising significantly in population size over the forthcoming decades, but also by its specific demographic structure. Like many large cities, London has a large share of people in the younger age groups – over 20% in the cohorts from 25-34 – but also a significant share of the youngest with around 7% of its population being 0 to 4 years old. Here is a population pyramid of London compiled from the 2011 Census data that has been released recently: Continue reading
According to a BBC News feature, “trends in migration are changing. Once, migrants from the same country tended to cluster in areas where they had relatives or friends. But new maps of England and Wales, reveal that for more recent migrants this is no longer the case” The maps of which this quote speak are a short series of cartograms created in collaboration of the BBC with the University of Sheffield in which we took a look at the first set of data from the 2011 Census in the United Kingdom (with much more detailed statistics due early next year). This is how some of the trends analysed by the BBC look like, using a gridded population cartogram of the country as a basemap for the lower maps shown here:
George Osborne’s autumn statement on the government’s budget rekindled the ongoing debate about the fairness of the coalition’s spending cuts. How does it look like if you take a look at the richest and the poorest parts of society? In an article for the “In Focus” section of Political Insight (December 2012, Volume 3, Issue 3) Danny Dorling and I plotted the geography of the wealthiest of the wealthy in the United Kingdom in comparison to poverty.
The map that I created for this feature displays the distribution of the top 1% of the wealthiest 1% according to information published by the agency WealthInsight, one of the companies trying to gather information on this part of the publication that is a prime target for exclusive marketing. Displayed in the map are data on people with assets in excess of US$30 million and where they have their prime address registered in the UK. The extent of the data is very limited because WealthInsight releases data for only 20 UK cities and regions based on postcode areas (Northern Ireland is a single postcode area which is why we did not correlate that data with Belfast’s overall population). Here we have superimposed that data on a population cartogram of the country, drawing circles with an area in proportion to the numbers of super-rich (in red) over people living in each city (in blue). Where they overlap, the circles turn into a purple colour. Where there are more super-rich people than population alone would predict, there is an orange ring around a purple core, as shown around London. Where there are fewer super-rich than the population of a city might predict, there is a blue outer-ring, as around Birmingham. The underlying map shows the distribution of poverty in the UK in five shades of grey.
Cities such as Leeds, Birmingham and Nottingham have fewer super-rich than might be expected – partly because they are not especially affluent urban centres but also, most probably, because their postcode does not include nearby areas such as the North Yorkshire stockbroker belt or the Cotswolds. Aberdeen, in contrast, has some multimillionaires: beneficiaries of the oil boom with an Aberdeen postcode who live some distance from that city. With Manchester it is hard not to speculate that a few extra footballers may have tipped it over the limit.
The British government announced a £9.4bn package of investment in the railways in England and Wales today, which – if it is realised as proposed – adds to the recent efforts to bring the motherland of rail transport up to the standards of many other countries around the world. The announcement comes in a year in which another major railway infrastructure project is widely discussed in the United Kingdom: “High Speed 2 (HS2) is a planned high-speed railway between London and the English Midlands, Northern England, and potentially the central belt of Scotland” (see Wikipedia).
Phase 1 of HS2 has been discussed widely earlier this year, after the latest route plans from London Euston to Birmingham/Lichfield were proposed as part of the HS2 public consultation.
The detailed route proposal shows the geographical location of some of the most critical parts of the line that has some considerable opposition amongst various interest groups. While a high speed rail network requires space for the fastest legs of the journey – usually to be found in the countryside – the shorter parts of the line are not without problems either: As the line connects the most populous areas of the countries, it has to go through some densely populated areas as well, which are less visible on the overview maps of the project (another map is featured on the BBC website). The following map therefore takes advantage of the fisheye perspective of a gridded cartogram that shows the proposed HS2 (phase 1) route plotted on an equal population projection map. The map also includes the average speeds in an area, demonstrating the (obvious) slowdown effect of densely populated areas, mainly London and Birmingham as the main destinations that this line connects in the initial stage. The map also shows nicely how the fastest part of the journey squeezes through the least populated corridor between these areas, and it also gives an impression of ‘travel time’, i.e. where one spends much of the time in a high speed train. Its not the landscapes that fly past the window while travelling at highest speed, but the urban landscapes that one creeps along quite slowly when leaving and approaching the major cities:

Changing times was the title of a session at this year’s Annual Symposium of the British Cartographic Society (not to be confused with the Society of Cartographers which will have its annual conference in September).
My contribution as a speaker in this session was titled Changing views of a changing planet. In the presentation I took a look at how changes in data and technology can provide alternative ways of mapping a globalised world, and mapping cities as the hotspots of globalisation. Continue reading
