The Proliferation of Border Walls

Border walls have become a prominent focus in the world today. At the time of the fall of the Berlin Wall in 1989, globally there were only about 15 border/security walls in place or under construction. In contrast, today there are more than 70 walls, with additional ones being proposed. Although human migration has been a fundamental characteristic of human history, walls are built and created primarily as barriers to control the mobility of people and commerce.
