Welcome back to Map Monday. This week we’re going to use cartograms to illustrate our story. Remember, cartograms are these strange looking maps that distort the shape of countries to reflect their relative contribution to the total amount being displayed.
Starting with world population, these cartograms show how populations have shifted as well as grown over time, as new places were discovered or colonized, as disease, war or climate changes decimated populations and/or people migrated elsewhere. I wish I could have found a more thorough collection of these cartograms for earlier times.
1 AD. World population was about 230 million people. Notice how many people were in Mexico and parts of South America compared to north of Mexico.
1500 AD. World population was about 460 million (doubled in 1500 years). Notice that the populations in Mexico and Peru had continued to expand, with sophisticated societies that had yet to encounter the Spanish conquistadors.
1900 AD. World population was about 1,600 million (3.5 times greater in 400 years).
1960 AD. World population was about 3,042 million (nearly doubled in 60 years).
2020 AD. World population was about 7,800 million (2.5 times greater in 60 years). (Worldmapper.org)
2050 AD. World population projected to be about 9,735 million (1.5 times greater in 30 years) Believe it or not, growth really is slowing. (Worldmapper.org)
Here are two cartograms for 2018, the first one showing where the bulk of the people are and the second one showing where the bulk of the wealth resides. No surprises.
Ecological footprint per country. The definition of an ecological footprint is the impact of a person or community on the environment, expressed as the amount of land required to sustain their use of natural resources. (Worldmapper.org)
CO2 emissions. The size indicates the amount of emissions while the colour indicates the amount per capita. China, the U.S. and India are the largest emitters, but on a per capita basis the U.S. emits twice as much CO2 as China and eight times as much as India, as does Canada, I’m sad to say. (Worldmapper.org)
Carbon footprint per country. This shows the carbon footprint of all goods and services in a country, including imports but not exports. Carbon emissions from major exporting countries like China show less of a carbon footprint than their emissions, while net importers such as the UK show a larger carbon footprint than they do carbon emissions.

Trash per person per country. I couldn’t find a cartogram of this piece of information, but I thought it belonged in this collection. (City-Data.com)
And finally, in the midst of all this enormous population and the increasing challenges we are throwing at our natural world, this cartogram attempts to pinpoint the existential risk to our planet’s plant and animal species, including both endangered and vulnerable species. The cartogram shows countries resized according to all animal and plant species assessed as being at risk of local extinction. (geographical.co.uk)
Sorry if I’ve overwhelmed you with too many maps, but at least you’ve got lots to contemplate until next time! 🙂
