South Africa: A people’s view

The ball is rolling, and the football world looks at South Africa and the South African people, who keep the world entertained with the unique Vuvuzela sounds. There are an estimated 49,320,000 living in the country, with an area of 1 221 037 square km this makes a population density of 41/km2. But the population is far from being equally distributed across the country. The following special worldcup edition of worldmapper’s gridded population cartograms shows where people are really living, and in which dimension the cities strike out in the population distribution. For easy orientation, all worldcup host cities are labelled. In addition elevation information is added to the map, so that one can see how many people live at which elevations.

The shape of the Football World

Jabulani, the official ball at this year’s Football Worldcup in South Africa is almost making its rounds across the pitch – only a few days to go until the first kickoff. But how much is it a real “World” cup? This map shows, whose game it has been since the first Worldcup in 1930. The countries in this map are resized according to the number of participations in the FIFA Worldcups (including the 2010 Worldcup). This year’s participants are coloured white, non-participants are black. The stars in a country indicate how often this country has won the Fifa Worldcup so far: All former champions are back on stage in South Africa.

Despite having 208 national associations in the Fifa, the map reveals the domination of Europe and South America in the tournament (in participation, as well as in the world cup winners), those regions with football being among the most popular sports. This inequality in the football worldcup can be explained by having a look at how the qualification process is organised: “For each tournament, FIFA decides the number of places awarded to each of the continental zones beforehand, generally based on the relative strength of the confederations’ teams” (see here). The football may be of global significance, but it is far from being a global game. The world map of football looks different than the map of the world…

The Real World at Night

The night view of the earth has become a very popular depiction of this planet. Although the NASA itself says that “The brightest areas of the Earth are the most urbanized, but not necessarily the most populated” many people mistake this view as a representation of the inhabited places on the globe. Our gridded population cartogram can help to get a better understanding of the relation of people and light. The following map is a reprojection of the earth at night that shows the nightview in relation to the population distribution. The gridlines are kept in a light colour and thus allow to identify those areas where the lines converge (representing the unpopulated regions). In contrast, the populated areas are given the most space, so that one can easily see which populated areas are literally illuminated at night – and where there are people living in darkness. The resulting map is an impressive picture of an unequal world, with large parts of Africa living in darkness, and the affluent countries in Europe and North America glowing in the dark:

2005-2010: Change?

Now that you know the results of the general election, and also had a look back at earlier elections, see here what has really changed: This is a short animation showing the British general election results in relation to the population distribution from 2005 transforming into the 2010 results and back in a loop:

The World in Crisis

The Greece’s financial crisis get that much attention these days, with the Guardian even setting up a live blog of the events happening related to it: Greece’s financial crisis – LIVE. This deserves another direct comparison of the previously shown two maps on Europe’s and World’s debt. Both map shows the countries resized according to their total external debt, whereas the colors indicate a country’s debt by gdp ratio. The maps are an outcome of a commissioned work for the Times newspaper, and putting those two slightly different values on one map may raise criticism, even if both values on it’s own make for a good depiction of the current state of the economic world – or the burden that some national governments currently face. Also, the data used must be judged carefully. Not just since Greece went on the global stage with its crisis it is quite obvious that economic statistics do not always reveal the real truth. Having said all that, these maps still draw an impressive picture of the current crisis in Europe and the world:

A population-centric map projection

Here is some material from a presentation at this year’s  AAG Annual Conference in Washington DC. The presentation People powered maps: A population-centric map projection was given in the session on Topics in GIS, Remote Sensing, and Spatial Analysis and showed some new works on our grid-based cartograms (as presented at GISRUK 2009 and ESRI UC 2009).
The following animation shows the transformation of a topographic map of the United States, ending in a grid-based population cartogram (and then reversing). Please notice that loading the animation takes a while on slower internet connections:
