The London Housing Bubble

Political InsightIn an article for the “In Focus” section of Political Insight (April 2014, Volume 5, Issue 1) Danny Dorling and I looked at the overheating of the housing market in London. The graphics that I created for this feature visualise the considerable changes that took place in recent years using data from an analysis reported in the Guardian: In 2012, the total value of residential property in London was reported to be £1.37 trillion. The value of housing in the capital dominated the UK housing market. By 2013, the value of London housing had risen to £1.47 trillion. Some £100 billion had been added in just one year, an additional £30,000 per property if the rise had been evenly spread out across the capital. However, just as within England, this increase was concentrated within certain areas, particularly those closest to the centre.
When London is redrawn with each borough sized according to the value of residential property, the largest borough becomes Kensington and Chelsea where the average home now costs £1.57 million. Westminster, with more housing but an average value of ‘only’£1.1 million is almost as large. Wandsworth, more typical at £527,000 a home, is more than three times the size of Newham despite having just 30 per cent more homes. However, even in Newham, the ‘cheapest borough’, the average property now sells for over £218,000.

London Borough Elections 2014

The London borough elections were held on May 22nd. A total of 1851 council seats (and also four mayoralties) were contested in 32 of the 33 boroughs in the British capital. The following map series produced for the Londonmapper Project shows the distribution of 1843 of the seats in the local councils as published on the London Councils election website (five seats in Tower Hamlets were still missing from the results, while the remaining seats are elected at postponed elections in a few of the wards). The maps show the individual distribution for each of the five main parties, i.e. Labour, Conservatives, Liberal Democrats, UKIP and Green Party (in order of their total number of seats) as well as Others (which are independent candidates as well as groups that only stood in individual borough, such as Tower Hamlets First who won 18 seats there). These are the new political shapes of London after what has been a small political earthquake in the country:

Hedgehogs and beyond: Introducing Londonmapper

LondonmapperGood things come to those who wait. Today we are officially launching the Londonmapper website, a project that I started working on following the completion of my PhD in 2011. Over the past 2 1/2 years we developed the scope of the project which aims to become a new Social Atlas of London, a project that has not been undertaken since Shepherd et al’s work in the 1970s. But it wouldn’t be me if this would be an ordinary mapping project. Londonmapper is a growing collection of all kinds of cartograms that map a wide range of data to give a comprehensive picture of the diversity in the city. Continue reading

Eurovision 2013 revisited

Eurovision 2013 revisited

Year after year in May Europe meets to celebrate one common guilty pleasure: the Eurovision Song Contest. More important in the outcome than watching the singing performances is the voting procedure: It sometimes appears as if points are not always related to the performance, but a reflection of European history and current events. That makes it interesting for detailed analyses (such as this detailed one by students of the Technical University of Denmark) regardless of whether one agrees with the quality and style of the contributions. The upcoming song contest takes place in Copenhagen, as Denmark was last years winner which can be seen in the following map of the total votes that each country received in the 2013 contest (see the bottom of this post):

But there is more to the results than the overall picture of the votes (Sidenote and warning: This blog post has a large number of maps embedded and may take longer to load up when viewing). Continue reading

China’s gender gap: Man-made problems?

Featured

CHINET“In recent decades, the world has witnessed the enormous economic, social, cultural and political development of China. As the most populous country in the world, China’s transition process influences directly one fifth of the world’s population and indirectly almost all the rest of the world. Chinese economic activities cover the whole globe, Chinese living overseas constitute the largest diaspora, and China’s political and economic influence is significant. On the other hand, China and its government face many challenges, as Chinese society as well as the environment are affected by these massive processes.” These challenges were the theme of a Conference on the Socio-Economic Transition of China at Palacký University in Olomouc (Czech Republic) where the opportunities and potential threats for China are discussed from an interdisciplinary perspective organized by the CHINET (Forging a scientific team and international networking in the field of Chinese Studies) project.
Part of that was an invited contribution which I prepared in collaboration with Adam Horálek of Palacký University. Our talk titled ‘Mapping Perspectives of Changing China’ presented a global as well as national context to the topic, framing China’s socio-economic place in the globalised world and highlighting some of the trends that started transforming the Chinese society considerably over the past three decades. While the most recent Census is not yet available in larger detail, we focussed on an analysis of some key aspects of the previous Census in more detail (and also discussed the quality and reliability of data from official statistics there).
The following map showing the gender gap was part of our slides (see below) and stands for one of the demographic challenges and existing tensions in the contemporary society. These are not only characterized by the changing age structures (with very distinct geographic patterns of ageing populations), but also by the considerable imbalance between the male and female population in most parts of the country. According to the most recent 2010 Census, this was at 1.18 males per female, and thus increased to the already high ratio that was stated 10 years before. In some regions, there are now over 130 men for 100 woman, with the fear (and sometimes reality), “that the excess will lead to increased sexual violence, general crime and social instability” (quoted from the Guardian). It is very much a man-made problem as in the early 1980s the ratio was at 108:100 and therefore only slightly above the natural rate, after which the 1979 introduced one child policy started having an effect that we see in its full extent today. This map, showing the sex ratio on an equal population projection (a gridded cartogram transformation where each grid cell is resized according to the total number of people in an area). It reveals, that the surplus of men is common throughout the country, while the opposite (a considerable surplus of women) is true for very few of the populated spaces in China (such as in the Shenzhen area of the Pearl River Delta where female migrants are the majority of workers under precarious employment conditions).
The authorities appear to become aware of the emerging problems, and according to the Guardian article, China’s “new Five Year Plan sets an ambitious target of cutting the ratio to 112 or 113 by 2016″. For the time being, the pattern in this map remains prevalent and puts pressure on a society that is feeling the full impact of China’s transformation to a new global player over the past decades.
