How do you draw a map of 100,000 places, of more than a million flows of people, of changes over time and space, of different kinds of spaces, surfaces and volumes, from human travel time to landscapes of hopes, fears, migration, manufacturing and mortality? How do you turn the millions of numbers concerning some of the most important moments of our lives into images that allow us to appreciate the aggregate while still remembering the detail?
The visualization of spatial social structure means, literally, making visible the geographical patterns to the way our lives have come to be socially organised, seeing the geography in society. To a statistical readership visualization implies using data. More widely defined it implies freeing our imaginations.
The Visualization of Spatial Social Structure introduces the reader to new ways of thinking about how to look at social statistics, particularly those about people in places. The author presents a unique combination of statistical focus and understanding of social structures and innovations in visualization, describing the rationale for, and development of, a new way of visualizing information in geographical research. These methods are illustrated through extensive full colour graphics; revealing mistakes, techniques and discoveries which present a picture of a changing political and social geography. More complex aspects on the surface of social landscapes are revealed with sculptured symbols allowing us to see the relationships between the wood and the trees of social structure. Today's software can be so flexible that these techniques can now be emulated without coding.
This book centres on a particular place and time; 1980s Britain, and a particular set of records; routine social statistics. A great deal of information about the 80s' social geography of Britain is contained within databases such as the population censuses, surveys and administrative data. Following the release of the 2011 census, now is a good time to look back at the past to introduce many new visualization techniques that could be used by future researchers.
Daniel Dorling, Professor of Human Geography in the University of Sheffield, UK Also Adjunct Professor in the Department of Geography, University of Canterbury, New Zealand and Visiting Professor in the Department of Social Medicine, University Bristol, UK. Daniel Dorling's research tries to show how far understanding the patterns to people's lives can be enhanced using statistics about the population. Part of this research involves developing new techniques to analyse and popularise quantitative information about human geography, in particular introducing the use of novel cartographic techniques into geographical research. In 2006, Daniel started working with a group of researchers on a project to remap the world (www.worldmapper.com). Respected in academia as a leader in his field, a Google search on his name also reveals how prevalent his voice is within the mainstream media. Daniel Dorling has published over 25 books and 400 papers. He is Honorary President of the Society of Cartographers.
