ABSTRACT
Danny Dorling was awarded his PhD from the University of Newcastle-Upon-Tyne in 1991 and the article under discussion here is one of the first to emerge from this work, and from his subsequent Rowntree and British Academy-funded research. He continues to be interested in social inequalities, and the mapping of census and other socio-demographic datasets. His recent appointment, from September 2013, as the Halford Mackinder Chair in Geography at the University of Oxford, is arguably one of the highest profile posts held by any author publishing in The Cartographic Journal. He focuses on the difficulties that stem from data collection and in particular considers the problems posed by the sampling frame. Dorling also considers the use of trivariate colour schemes, deploying red, blue and yellow hues to map out occupational difference. He then considers the mapping of change deploying frozen wards as a device to visualize difference between the 1981 and 1991 censuses.
