This is the key visualisation from my PhD thesis it is an abstract representation of how we can understand migration related diversity as both multi-layered and in relational terms. The graphic displays the different patterns of homophily each associated to one of my 55 respondents. Homophily scores measure how much a focal individual is the same as his or her social contacts on some aspect.
Each column shows information about one personal network and the colour of each of the rectangles in the rows describes the proportion of social contacts a respondent named who were in the same category as her or him. The darker the shading the more alike that respondent was with his or her social contacts, This ‘heat map’ thus allows to display multiple aspects of superdiversity in a relatively simple way that does, however, not reduce the complexity of relational diversity.

This graphic taken from a recent publication in Ethnic and Racial Sudies shows the increases in migrant origin groups in different countries:
"[The graphic] portrays four decades of migration diversification. Each larger rectangle represents one decade and is subdivided into smaller rectangles. Each smaller rectangle shows one country; the size of each smaller rectangle reflects the number of countries of origin for migrants (here with at least 500 people per country of origin). Only those countries with at least twenty-five different groups are included in the figure. Over the decades, we can see a clear, worldwide rise in the number of migrant countries of origin experienced in many countries of the world; the small rectangles in 2000 are more numerous (more countries count more than twenty-five groups of more than 500 individuals) and the size of the decennial rectangle also increases. In addition, Figure 1 shows that these processes of diversification are dynamic and that some countries – granted fewer – are shaded lighter, indicating a decrease in the number of groups from one decade to another. (Meissner and Vertovec 2014: 3)"
This maps shows the 'Paperwork inequalities' that are the result of current global arrangements allowing people from different countries visa free access to substantially divergent numbers of other countries. Passport holders from countries that are shaded darker have visa free access to more countries than do those from countries that are shaded lighter.

One of my research interests is to make sense of complex social configurations through the use of data visualisations. This page is intended as portfolio of data visualisations and infographics I personally designed or which are part of my research.
