This interactive data graphic explores annual migration flows to and from selected OECD-countries in the years 1970-2007. Underlying data has been provided by the United Nations Population Division.
The visualization illustrates the evolution of »Superdiversity«, a term coined by Steven Vertovec to reflect a level of societal complexity far beyond anything observed in the world before. During the last two decades more people than ever have moved between different locations worldwide.
This process thus becomes approachable in an interactive, visual way.

Visualization of societal diversity in 225 countries in the census-years 1960, 1970, 1980, 1990 and 2000. For each country in the list, population is grouped by origin, i.e. country of birth or alternatively - in a number of cases - by citizenship. Over decades, an emergent pattern of increasing diversity of societies can be observed. The underlying data originates from the Global Migration Database, a joint project of a research group of The World Bank and the UN Population Division.

Same data as above, from an inverse perspective. Where do people leaving their country of birth move to? What countries or regions are the sources of »Superdiversity«?
