The UK general election is fast approaching. Following the first almost-debate of the would-like-to-be Prime Ministers the battle for the ‘correct’ interpretation of the state of the nation has come into its final stage. Statistics are easy to twist, and there is never an absolute truth in them. In a collaboration with the Office for National Statistics I was involved in the creation of a little interactive visualisation feature that sheds light on some key statistics that show life in the constituencies around the country. Using a conventional map and a hexagon cartogram of the United Kingdom we looked at house prices, income, public sector employment, education, age, migration, and health which can be interactively explored and compared in both map views. The following map is one example from that feature, showing the share of people not born in the United Kingdom:
Make it happen is this year’s theme of International Women’s Day. The day is Internationally the day is celebrated every year on March 8th since 1911 and in 1917 demonstrations in the context of the Women’s Day lead to the outbreak of the Russian Revolution. What had started as a socialist event to recognize women’s economic, political, and social struggles and achievements has now lost this ideological connotation. Today it is rather regarded as an opportunity to raise awareness for the inequality women still experience in all societies.
In some countries the day is still an official holiday, such as in Russia and other former socialist republics, but also in Afghanistan, Angola and Eritrea. In China, Madagascar, Macedonia and Nepal it is a holiday solely for women.
Gender inequality remains a pressing challenge globally and is seen as a major barrier to human development which is why the UN’s Human Development Index (HDI) has a specific indicator to take these problems into account. The Gender Inequality Index (GII) measures gender (in)equity in health, education, work and politics.
The following map shows one indicator from the current GII that highlights the political representation of women in parliaments worldwide measured by the share of seats in parliament (with data for 2013). The map uses an equal-population projection which gives every person on the planet an equal amount of space:
“20’s Plenty for Us is a voluntary organisation that campaigns for the introduction of a default 20 mph (32 km/h) speed limit for residential streets and urban streets. By seeking to obtain implementation across a complete local authority or community then the organisation believes that worthwhile speed reductions can be achieved without the usual physical calming features.” (Wikipedia) In collaboration with Rod King of 20’s Plenty and Danny Dorling of Oxford University we looked at how far the campaign has gotten so far with convincing local authorities to implement a speed limit of 20 mph in residential areas. Today 12.5 million people live in areas where cars travel more slowly. Although nationally pedestrian deaths on the road are still rising, it marks a first step towards more road safety by a very simple measure. Looking at the spatial patterns, the implementation can be observed all across the United Kingdom, though there appear to be very little on a conventional map. Looking at the issue through an equal-population projection reveals the real extent and puts a spotlight on these areas that really matter for this measure: the most densely populated areas. Here it can be seen that the majority of Scottish people live in areas where 20 mph zones are prevalent, just as the Liverpool-Manchester region (and Sheffield) have seen very successful campaigns, while in other parts of the country the red patches are still covering very large shares of the population:
There is a long tradition in the emotional relationship between people and forests. We can get an understanding of the extent of the global tree cover from satellite sensors such as NASA’s MODIS
Calculating the average tree cover in an area allows us to estimate the extent of the world’s forests. Forest landscapes can be mapped in various ways and is often done in conventional maps. However, much of the land area is not covered by forest and the few remaining untouched forest landscapes keep shrinking while deforestation continues.
The first two chapters of the Gospel of Luke in the Bible state that the birth of Jesus took place at the time of the census: “In those days a decree went out from Emperor Augustus that all the world should be registered. This was the first registration and was taken while Quirinius was governor of Syria. All went to their own towns to be registered.”
Believing in the religious background of the nativity story or not, evidence for the Census of Quirinius following Caesar Augustus’ decree exists beyond the bible. However, despite all recent initiatives to open up public data, the Census results of back then have not seen the light of day…until now!
This Christmas we can reveal the results of the Census of Quirinius following a freedom of information request to the Roman Empire (well, and following some more in-depth analysis within the Worldmapper project using Angus Maddisons studies). This is how the world looked in the year 1 CE (3761 Hebrew calendar, 18.104.22.168.3 Mayan calendar, 544 Buddhist calendar):
Wishing everyone a happy new year!
This year’s World Science Day for Peace and Development, established by UNESCO in 2001, is promoting Quality Science Education: ensuring a sustainable future for all. According to UNESCO, the day “offers an opportunity to mobilize various partners to highlight the important role of science in society and to engage the wider public in debates on emerging scientific issues and the relevance of science in their daily lives”. While the importance of science is less disputed, the reality of ensuring scientific progress through excellent academic education remains a highly unequal matter, as many global academic rankings show.
This feature is an update to the work originally compiled last year in collaboration with Phil Baty of Times Higher Education and which first appeared in the World University Rankings. In this update I put the latest rankings results for 2014/15 into a human and economic perspective. The first two maps show the top 200 Universities from the Ranking displayed on two different kinds of gridded cartograms:
