World Population Distributed by Latitude and Longitude

David Taylor and the team at CityMetric have recently posted a simple and effective chart to show that the population of Canada is not as north as we might think. This reminded me of a another map, that we posted almost five years ago ....

Bored of those traditional population maps, I've posted this inventive chart/map of the world population distributed by Latitude and Longitude. It was created in 2008 by Bill Rankin, who you might know from his website Radicalcartography.

The real-time city? Big data and smart urbanism

Professor Rob Kitchin is one the leading scholars on issues that arise at the intersection between big data, ubiquitous computing and smart cities (how software mediates everyday life in cities, more broadly). He is also one of the main researcher at the Programmable City project.

Rob delivered last year an interesting presentationat OII here at Oxford, where he gave a good summary of the scholar discussion on big data and smart cities, presenting a critical view on the political dimension of smart urbanism. I've embedded the talk in this post, but you can also watch it here. Rob's presentation was based on this paper: 

Kitchin, R. (2014). The real-time city? Big data and smart urbanism. GeoJournal, 79(1), 1-14. (ungated version). 

‘Smart cities’ is a term that has gained traction in academia, business and government to describe cities that, on the one hand, are increasingly composed of and monitored by pervasive and ubiquitous computing and, on the other, whose economy and governance is being driven by innovation, creativity and entrepreneurship, enacted by smart people. This paper focuses on the former and, drawing on a number of examples, details how cities are being instrumented with digital devices and infrastructure that produce ‘big data’. Such data, smart city advocates argue enables real-time analysis of city life, new modes of urban governance, and provides the raw material for envisioning and enacting more efficient, sustainable, competitive, productive, open and transparent cities. The final section of the paper provides a critical reflection on the implications of big data and smart urbanism, examining five emerging concerns: the politics of big urban data, technocratic governance and city development, corporatisation of city governance and technological lock-ins, buggy, brittle and hackable cities, and the panoptic city.

Here are some stats that show a summary of the blog over the past year. Please, feel free to drop me a line (email or comments) with suggestions on how to improve Urban Demographics blog. If you have any criticisms, please direct them to this other blog here.

Where do readers come from? (180 Countries, or 5,433 Cities)
  1. United States (34.3%)
  2. Brazil (10.7%)
  3. United Kingdom (9.5%)
  4. Canada (3.7%)

Dubai at High Speed

Rob Whitworth is among the most prominent film makers and with some of the most amazing time lapse videos. I first got to know Rob's work thanks to Aaron Renn, who gathers a great collection of time lapse videos on his website, The Urbanophile.

I try to follow Rob's work since I watched his great video on the frenetic traffic in Ho Chi Minh City (Vietnam) in 2011, one of my favorites. 

Since then, Rob has made some beautiful videos of Shanghai, Barcelona, Kuala Lampur and ! Pyongyang, in North Korea. More recently, he came up with a stunning video of Dubai at high speed. Best viewed full screen and in high definition.

The Growing and shrinking populations of Europe, 2001-2011

Jonn Elledge (editor of the great website City Metrics) points out to this amazing map showing the population changes of every European municipality between 2001 and 2011. The colors represent average annual population variation, where red gradients represent growth rates between 0 and 2 per cent or over, and blue gradients represent depopulation rates of the same magnitudes. Yellow areas are stable.

Despite converging trends of low fertility and mortality rates in European countries, the map shows a tremendous diversity in the population dynamics of European municipalities, mostly driven by migration trends. A common trend in almost all countries, though, is the population growth in cities and suburban municipalities. This population shift to cities also present remarkably different patterns in different countries, what probably gives some good material for researchers working on spatial demography and urbanization. There are plenty other interesting things to comment on this map but this would go beyond my capacity and my procrastination time limit .

The maps was created by the German Federal Office for Building and Regional Planning (BBR) and you can check a high definition version of the map here.
