In Japan, the threshold is 50, Far from allowing an apples to apples comparison, those differing thresholds mean that putting Danish cities and Japanese cities side by side would be more like a blueberries to watermelons comparison. For starters, the claim that the world became majority urban in for the first time in human history? Not true. According to the new definition, which defines a city as a contiguous geographic area with at least 50, inhabitants at an average population density of 1, people per square kilometer, about 48 percent of humanity lived in cities as of Why the sudden decrease?
Because over a quarter of the planet lives in towns — like those Danish hamlets of odd souls — a category that the world has largely ignored in its preference for an urban-rural binary, the idea that someone either lives in a city or in the countryside.
But in defining this third category, Dijkstra argues, we have a more accurate understanding of what the world really looks like — a gradient between rural farmers and city dwellers. Those towns, moreover, are the cities of the future.
This more accurate picture matters because simple stats like a majority-urban planet justify the allocation of enormous sums of foreign aid and domestic spending. In Egypt, places listed as rural agricultural settlements on official maps are actually cities as large as , , but making the official change puts the government on the hook for everything from schools to courthouses.

Economic contraction and natural disasters have also contributed to population losses in some cities. A few cities in Japan and the Republic of Korea for example, Nagasaki and Busan have experienced population decline between and Several cities in countries of Eastern Europe, such as Poland, Romania, the Russian Federation and Ukraine, have lost population since as well.
In addition to low fertility, emigration has contributed to the lower population size in some of these cities. Globally, fewer cities are projected to see their populations decline from today until , compared to what has occurred during the last two decades. The rural population of the world has grown slowly since and is expected to reach its peak in a few years. The global rural population is now close to 3. India has the largest rural population million , followed by China million.
Today, Cairo, Mumbai, Beijing and Dhaka all have close to 20 million inhabitants.
