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:
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:
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:

The British monarchy is celebrating the 60-year reign of Queen Elizabeth II as the official head of state of the United Kingdom. The British Monarchy reaches beyond the boarders of the United Kingdom, making the Queen a constitutional monarch of (currently) 16 countries of the 54 members of the Commonwealth. Celebrations of the Diamond Jubilee will therefore not only be a matter of British subjects, a term which adds to the sometimes confusing geographical realities related to Britain. The epicentre of the events is of course the United Kingdom, especially the capital city London where the celebrations peak this (extended) weekend. The media is well prepared to get the global attention aligned to London ahead of the Olympics. In ongoing difficult economic times these upcoming events are a welcoming distraction for politicians to keep the population quiet.
To put the people back at the centre, here comes a new look at the population of the United Kingdom. The following map builds on the gridded population cartogram that I published on this website before (e.g. at this comparison of a choropleth density map and a cartogram, in this report of the Royal Commission, at this comparison of the different parts of the UK, or in this first London feature on this website). The new gridded population cartogram is a revised version using a much higher resolution population grid like in this population map of Germany. The data comes from the LandScan database which allows to map even more detail in the population distribution, which is why this new map shows a higher variation of population densities within the most densely populated areas. The map is the most detailed gridded population cartogram of the United Kingdom produced so far, which allows us to see even smaller cities in their population context. The map is an equal population projection where each grid cell is resized according to the number of people living there. It shows human shape of the United Kingdom in HD resolution as never before:

The old Mayor is the new Mayor of London as Boris Johnson secured a second term in office at this month’s election in the British capital. This left contender Ken Livingstone in second place at a campaign that was put the two personalities more into the spotlight than the underlying politics. Beyond the decision between Boris and Ken the elections provided an insight into how much the political patterns have changed since the last election in 2008. As a comparison to the feature published before the election, I created the same map series from the 2012 election results, giving an updated view of the political landscapes of London of all contestants and their respective political parties. This year’s election saw fewer candidates and resulted in a more polarised picture between the two main parties (Conservative and Labour) and the smaller ones. Nevertheless, the individual vote distributions of all participating parties (and candidates) result in specific patterns that correspond to the preferences of the population in London. Majorities of votes from each part of the political spectrum – from right to left wing views – are significantly distributed, not only when it comes to differences between Labour- and Conservative strongholds, but also for the smaller parties, as the following map series demonstrates by mapping the individual vote shares accordingly. The results are displayed on a gridded population cartogram of London (election data provided by London Elects):

Demographic trends in the United Kingdom, such as these discussed in the report on Demographic Change and the Environment, show an ongoing population growth in the south-east of England. With London being the dominating city in the UK’s economy, this is little surprising, as key industries but also most key institutions are still located in the capital city. This is one major reason why the southeast is like a population magnet that will have to find strategies to cope with an increasing population if these conditions persist. Demographic trends do also predict a slowdown in population increase over the next decades, with an aging society and declining birth rates as they can already be observed in Germany or most Easter European countries. All trends include challenges for policy making and planning, which is why population projections play a key role for urban planners to face future challenges in their decision-making. The Greater London Authority as the key administrative body for the most populous area in the UK (see map) released such projections on borough level to the year 2031, including population estimates for the past years (see London Datastore) which I have used for some of my research recently. Following a series of population maps created from this data by Spatial Analysis I used this data to create a population cartogram animation for the 30 years covered by this data which shows the changing shares of the population within the boroughs of Greater London, including a colour code for the net migration (taking population change, births and deaths into account). This is how the London population trends look like: Continue reading
