Maps seemed to be everywhere in 2013, a trend I like to think we encouraged along with August's
40 maps that explain the world. Maps can be a remarkably powerful tool for understanding the world and how it works, but they show only what you ask them to. You might consider this, then, a collection of maps meant to inspire your inner map nerd. I've searched far and wide for maps that can reveal and surprise and inform in ways that the daily headlines might not, with a careful eye for sourcing and detail. I've included a link for more information on just about every one. Enjoy.
1. Where the world's people live, by economic status

Those dots represent people: the brighter the dot, the more people. The color shows their country's average income level: blue is richest and yellow is poorest. I want to start with this map because it's a reminder that the world is first and foremost made up of people; to me, the best maps are primarily about showing us people, not politics or geography. It's also a way of looking at the divisions in the world other than by political borders; that's a theme we'll come back to. (One caveat to this map: it doesn't show economic variations within countries, just the national averages.)
2. How humans spread across the world

Human beings first left Africa about 60,000 years ago in a series of waves that peopled the globe. This map shows where those waves of migration went and when they occurred (the "40K" over Europe means humans arrived there about 40,000 years ago). You can see that humans have the most history in the Middle East, India and of course Africa itself (the map does not show the much longer history of migration within Africa). We are relative newcomers to the Americas, one of the reasons it has not until very recently been as densely populated as other parts of the world.
3. When the Mongols took over the known world

The Mongol conquests are difficult to fathom. Although their most important technology was the horse, they conquered much of the known world from China to Europe, a series of wars that killed tens of millions of people, then a substantial chunk of the world's population. The Mongols also established what may well have been the largest empire in history until the British surpassed them six long centuries later. It's difficult to understate how much we still feel their impact today; the country we know of today as Iraq has
never fully recovered from the 1258 sacking of Baghdad, which until then had been a center of global wealth and knowledge.
