Nativity map: The Census of Quirinius revealed

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, 7.17.18.13.3 Mayan calendar, 544 Buddhist calendar):

World University Rankings 2014/15

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:

Growing old: European Population Pyramids

Featured

“A population pyramid, also called an age pyramid or age picture diagram, is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the world), which forms the shape of a pyramid when the population is growing.” (Wikipedia)

Demographies of China

Featured

This week I joined the Department of Asian Studies at Palacký University Olomouc (Czech Republic) as a visiting lecturer by invitation of the CHINET project. In my lecture about New Geographies of China I built on the work I have presented earlier this year at the Conference on the Socio-Economic Transition of China at the same place, teaching the students not only how China’s position is in the global context of demographic, social and economic change, but also how we can visualise this in novel ways. The following three maps are an extract from my presentation that gave an overview of this lecture.
The maps show the distribution of the different age groups in the country divided into children (age 0 to 14), working age (age 15 to 64) and elderly (above age 64) as they are counted in the official Chinese Census released by the National Bureau of Statistics. As the most recent Census figures have not been released at the same level of detail, the following three maps show the state of 2000. Here is an animated version of the three maps showing all three groups one after another (the individual maps are displayed below):

Germany’s Population Growth and Decline

Some time ago I have published an analysis of the changing demographies of Germany on this website (see also the map at the end of this post). I used the data from this analysis to develop some further cartogram visualisations that put the increase and decline into the focus, showing how heterogeneous these trends are evolving spatially in Germany. The following maps show gridded cartogram transformations of population change in Germany in which each grid cell (representing an equal physical space) is resized according to the total estimated population increase (right map) or decline (left map) in the period of 1990 to 2010. They show, how population patterns chances in the first two decades after reunification:
