Fair Share Estimate #4 – REAL POPULATION DENSITY

Fair Share Estimate #4 – REAL POPULATION DENSITY

The chart provides one way to estimate what is fair when the nations of the world try to figure out how to help Syrian refugees. How many should go where? This is NOT A POLICY PROPOSAL! This is a sketch to help think.

It’s simply a list of the 25 largest nations, the 25 nations with the most arable land, and the 25 nations with the largest populations. It gives the REAL POPULATION DENSITY of each nation as of 2014 (CIA World Factbook).

“Real population density” requires a little effort to understand. But consider Antarctica. There aren’t a lot of people at the South Pole. In 2005, there was the largest crowd ever wintering over there: 86 people! With five million square miles to share, that’s over 50,000 square miles apiece. But there’s not a lot of food, not a lot of shelter, not much light for months. So everybody was hanging out at one dinky little station, and it was crowded.

“Real population density,” also called “physiological density,” refers to the population on the arable land. Population is not a useful measure by itself; nor is land by itself; nor is arable land by itself. But real population density is an effort to put these factors together. The measurement has an awful history; it is used in population control presentations all the time. So if you use it, use it carefully.

There are two charts below. The first chart below shows the real population density of 43 nations (the largest, the most populous, and those with the most arable land). Real population density is population divided by arable land. The chart shows population, arable land, real population density, and real density as a percentage of the global average. The final column is “capacity,” the theoretical population of that nation is the real population density matched the global average (arable land X the global average of 463).
