The problem with maps. Mandatory Accompanying Playlist The World The world is round. Google says so. Block by Block, Brooklyn’s Past and Present On my weekly walk to get groceries, I pass a row of brownstones — some well-kempt and majestic, some fossil-like and crumbling — bookended by a gleaming, square-windowed silver tower.

World Migration Map - Data Visualization by Metrocosm This map 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.
