Why Canada and Australia Are Empty for Opposite Reasons

Canada and Australia explained: two countries almost empty for completely opposite climate reasons — one frozen, one bone dry. Canada covers about ten million square kilometers and Australia about seven point seven million, together bigger than all of Europe, yet both nations crowd into a tiny fraction of their own land. About seventy-five percent of Canadians live within one hundred sixty kilometers of the US border, pushed south by the Canadian Shield, permafrost covering roughly half the country, and the frozen expanse of Hudson Bay. About eighty-five percent of Australians live within fifty kilometers of the coastline, pushed outward by deserts like the Simpson, the Great Victoria, the Great Sandy, and the Tanami. This video maps both patterns city by city, from Vancouver, Toronto, and Montreal along the 49th parallel to Perth, Adelaide, Melbourne, Sydney, and Brisbane ringing the Australian coast. In this video you'll learn: • Why is most of Canada's population concentrated near the US border? • What is the Canadian Shield and why can't you farm on it? • Why does permafrost make northern Canada so hard to settle? • Why are Yukon, the Northwest Territories, and Nunavut almost empty? • Why is the Australian outback so empty? • What deserts cover the center of Australia? • Why do almost all Australians live near the coast? • Why is Perth one of the most isolated major cities in the world? Both emptiness patterns trace back to physical geography more than history. Glacial scouring left the Canadian Shield almost soil-free and locked much of the country under permafrost, while Australia's interior sits under a permanent dry high-pressure belt that starves it of rain. The geography of Canada and the geography of Australia explain population density, borders, and trade routes better than politics ever could — this is a map explained through climate and geology, not opinion. ⏱ Chapters 0:00 Canada and Australia Population Maps 0:40 Canadian Shield Bedrock and Boreal Forest 1:27 Yukon Northwest Territories and Nunavut 2:11 Frozen Hudson Bay and Far North 2:42 United States Border and Vancouver 3:10 Canadian Prairies and 49th Parallel 3:36 Toronto and Montreal Metropolitan Corridor 4:34 Arid and Semi-Arid Australian Interior 4:58 Simpson Great Victoria and Tanami Deserts 5:43 Murray-Darling Basin and Inland Rivers 6:08 Isolated Alice Springs Desert Settlement 6:33 Dense Australian Coastal Population Ring 6:57 Isolated Perth Western Australia Metropolis 7:28 Melbourne Sydney and Brisbane Coastal Cities 8:35 Canada Border Band Australia Coast Ring 9:43 Canada and Australia Total Populations 10:59 Future Climate Shift in Canada and Australia Key places & terms: Canadian Shield · Permafrost · Hudson Bay · Yukon · Northwest Territories · Nunavut · Vancouver · Toronto · Montreal · Saint Lawrence Lowlands · 49th parallel · Simpson Desert · Great Victoria Desert · Great Sandy Desert · Tanami Desert · Lake Eyre · Murray-Darling Basin · Alice Springs · Perth · Sydney New animated-map explainers on geography and geopolitics — subscribe so you never miss the next map. #geography #maps #geopolitics #canada #australia Imagery: NASA Blue Marble (public domain) · Relief: SRTM/NASADEM (AWS Terrain Tiles) · Map data: Natural Earth Photo credits (Wikimedia Commons, file titles searchable there): • US-Canada Border in Lubec, Maine — Andy8Kahn (CC BY-SA 4.0) • Cape Bridgewater Coastline 001 — Mattinbgn (talk · contribs) (CC BY 3.0) • Naturlandschaft bei Ragueneau, Region Manicouaga — Marc-Lautenbacher (CC BY-SA 4.0) • Taiga and bedrock in Yellowknife — Daniel Case (CC BY-SA 3.0) • Permafrost in Herschel Island 015 — Boris Radosavljevic (CC BY 2.0) • Yellowknife, Northwest Territories — Quintin Soloviev (CC BY 4.0) • Vancouver skyline — Murray Foubister (CC BY-SA 2.0) • Mount Royal Montreal View — Paulthelawyer (CC BY-SA 4.0) • Sunset Toronto Skyline Panorama Crop from Snake — Jchmrt (CC BY-SA 4.0) • Andado2 - Christopher Watson — Christopher Watson (http://www.c (CC BY-SA 3.0) • Murray River at Boundary Bend — Scott Davis (CC BY 2.5) • Dead unidentified Freshwater Mussel on the dried — Bidgee (CC BY-SA 3.0) • MacDonnell Ranges, NT — Andy Mitchell from Glasgow, UK (CC BY-SA 2.0) • Adelaide city centre view — Normangerman at English Wikipedi (CC BY-SA 3.0) • View of Perth and Perth Stadium down the Swan Ri — Calistemon (CC BY-SA 4.0) • Sydney Opera House and Harbour Bridge Dusk (2) 2 — Benh LIEU SONG (Flickr) (CC BY-SA 4.0) • Story Bridge, Brisbane City views, 2021, 02 — Kgbo (CC BY-SA 4.0) • Shield P7170062 — Chris Light (CC BY-SA 4.0) • April Sea Ice over Hudson Bay (MODIS 2022-04-18) — MODIS Land Rapid Response Team, (Public domain) • Thawing on James Bay (MODIS 2025-05-07) — MODIS Land Rapid Response Team, (Public domain) • Lake Ontario Shoreline — SAF1999 (CC0)
