Mapping Migration

Here are four excellent web maps / infographics showing international and national migration. The underlying technologies are also quite interesting and the different approaches to data visualization.

• MigrationsMap.Net is a classic web map, nicely executed in HTML5.
• Immigration Explorer combines space and time data from the U.S. Census in a classic NYT style.
• Restless America is not a 'map' but instead an interactive infographic.
• Origins and Destinations of the World’s Migrants, from 1990-2015 shows the flows of people in and out of countries.
