Animated chord diagrams of estimated migration flows from 1990-1995 to 2015-2020 based on six different methods.

Direction of the flow is indicated by the arrowhead. The size of the flow is indicated by the width of the arrow at its base. Numbers on the outer section axis, which give the size of migration flows, are in millions of individuals per five-year period. Sector axis limits are based on maximums over all estimation methods and all five-year periods.

Plots for fixed_all.mp4, fixed_all.gif, fixed.mp4 and fixed.gif use the first version of the data set (as published in the Scientific Data paper).

Plots with the single chord diagram use the fifth version of the data set, see https://doi.org/10.6084/m9.figshare.7731233.v5
