VSJF-Refugees Migration 1898-1975 in Switzerland
We developed an interactive visualization of the migration flow of (mostly jewish) refugees migrating to or through Switzerland between 1898-1975. We used the API of google maps to show the movement of about 20'000 refugees situated in 535 locations in Switzerland.
One of the major steps in the development of the visualization was to clean the data, as the migration route is given in an unstructured way. Further, we had to overcame technical challenges such as moving thousands of marks on a map all at once.
The journey of a refugee starts with the place of birth and continues with the place from where Switzerland was entered (if known). Then a series of stays within Switzerland is given. On average a refugee visited 1 to 2 camps or homes. Finally, the refugee leaves Switzerland from a designated place to a destination abroad. Due to missing information some of the dates had to be estimated, especially for the date of leave where only 60% have a date entry.
The movements of all refugees can be traced over time in the period of 1898-1975 (based on the entry date). The residences in Switzerland are of different types and range from poor conditions as in prison camps to good conditions as in recovery camps. We introduced a color code to display different groups of camps and homes: imprisoned (red), interned (orange), labour (brown), medical (green), minors (blue), general (grey), unknown (white). As additional information, to give the dots on the map a face, we researched famous refugees who stayed in Switzerland in the same time period. Further, historical information were included to connect the movements of refugees to historical events.
