An impressive data visualization project shows the estimated net immigration (inflows minus outflows) by origin and destination country between 2010 and 2015.
Blue circles = positive net migration (more inflows). Red circles = negative net migration (more outflows). Each yellow dot represents 1,000 people. Hover over a circle to see that country’s total net migration between 2010 and 2015. Click a circle (or tap the circle twice on mobile) to view only the migration flows in and out of that country.
