Interactive iris like graphics show world migration flows since 1970

As reported by the Guardian, the Max Planck Institute for the Study of Religious and Ethnic Diversity has created an interactive graphic chart showing migration flows between countries between 1970 - 2007.

The visualisations depict the numbers of migrants moving in and out of 28 countries from all around the world, with the flows broken down by destination (for emigrants) and nation of origin (for immigrants).

The skeleton of each nation’s graphic comprise three concentric circles. Lines outward signify emigration, while those stretching inwards from the middle represent immigrants. The length of the lines corresponds to the amount of people forming that particular flow, while the colour corresponds to the partner country's location.

The lines representing flows with African countries are green, with Asian nations orange and Caribbean ones pink. Central American lines are blue, Northern American salmon, South America turquoise, European ones yellow, Oceania purple, and others grey.

Users can alter the line scales to better illustrate the differences between migration flows to and from a specific country. They can also use the scrolling timeline to select a year from which to see data.

The public can click on an individual line to bring up the total amount of people emigrating to and immigrating from the corresponding partner country for a given year. People can also pick whether to show data for citizens of the specific country or foreign-born individuals.
