In 2015, the percentage of the population 65+ years old in OECD countries was 28%, this figure is expected to rise to over 50% by 2050. The graphic above display where each country stands or the population projects in the next 40 years. Japan, Italy, and Greece are already the oldest countries with 46%, 37%, and 35% of their population over 65 years old (in 2015), by 2050 these countries are projected to continue to lead with 78%, 75%, and 73% respectively. This is amazing to imagine. Think about it, Japan in 2050 with nearly 80% of its population over 65 years old. What will a country like that look like?
On the other end of the spectrum in the OCED – Mexico and Turkey are looking stable with only 35% and 37% of their population above 65 years old. This figure is approximately already what the average OCED country is at. The US, Canada, Australia, and New Zealand all look stable with a healthy inflow of immigrants that aid in slowing the growth in elderly people as a fraction of the overall population. Side note: South Korea is projected to undertake the most drastic population change. It is currently one of the youngest countries in the OCED, but in 40 years it will be among the oldest – moving from 19% of its population over 65 to over 70% by 2050.
The map above is color-coded by each country’s largest export. Most countries are grouped into a few categories: Fuel, Food, Transportation, Electronics, or Mineral exports. Europe is a large exporter of cars, East Asia of Computers/Electronics, Sub-Sahara Africa of Minerals and Food. The largest export in the world and the one involved with the most countries is Petroleum/Fuel. It is the largest export in the Middle East, North Africa, India, Russia, the US, and Canada.
The map above is color-coded by each country’s largest import. Most countries are grouped into a few categories: Fuel, Food, Transportation, or Electronics imports. The western world’s (the US, Canada, western Europe, Australia) largest import is Transportation/Cars. Developing Asia and Latin America’s largest import is Fuel/Petroleum. Northern Africa is an importer of Food and Southeast Asia an importer of Electronics.
Did you know that California (39 million) has more population than Canada (36 million)? The map above displays the area comparison and map below shows how Canada’s population would fit into California. For example, most Canada’s population is concentrated in the two provinces of Ontario and Quebec – these provinces have approximately the same population of southern California. Even though Canada has an area larger than the entire United States, its population can fit into California with room to spare. Side note: California also has a substantially larger economy with a 2.6 trillion nominal GDP compared to 1.5 trillion for Canada (2017).
The United State and South Korea are outliers in the developed world with male circumcision rates above 50%. Most of the world’s countries and population are uncircumcised, many with percentages around only 10%. The map above displays each country’s male circumcision rate.
Australia is considered one of the world’s six continents, although some consider it the world’s largest island. If this is the case, the map above displays Australia’s land area compared with the next largest islands in the world. The next closest (in area) to Australia is Greenland with an area only 27% the size, followed by New Guinea at only 10% the size of Australia. The top 20 largest islands by area are displays and listed on the right.
Above is a map of Europe displaying whether a country has a GDP per capita less than or greater than Turkey. The data is from the IMF in Oct 2017. Turkey has a GDP per capita of $24,912 at Purchasing Power Parity (PPP). The data displays the income divide Europe where all of western Europe and Russia (labeled in Blue) have a higher standard of living than Turkey and most the former USSR and former Yugoslavia countries (labeled Red) have a lower standard of living than Turkey. The income differences help to explain some of the internal migration within Europe.
In the largest and most competitive tech companies, the average tenure by employees is approximately two years. The chart above displays the average number of years an employee spent working for various large tech companies.
The map above displays the western hemisphere and shows with extending a horizontal line (longitudinal) which country is across the ocean from it. This is an interesting perspective from which to view the world given that these matching countries are likely to share the same climate and culture based on their position in the world. It’s amazing to see the north-south size of Africa projected onto the Americas – Its northern reach with Morocco across from (approximately) Washington DC in the United States to its southern point with South Africa across from Buenos Aires. Another stunning display is the north-south size of Japan which it the closest country to virtually the entire west coast of the US.
Above is a scatter plot of height (y-axis) and weight (x-axis) for professional athletes in the five major sports in the United States: NFL, NBA, MLB, NHL, and MLS. The data points displayed are averages at different positions in the sport. For example, the average point guard in the NBA is 6’2” 185 lbs whereas the average center is 6’11” 250 lbs. The average US man (approximately 5’9” 190 lbs) is labeled in white. Keep in mind that only 14.5% of US men are taller than 6 foot and only 3.9% are taller than 6’2”. Given that the average height for the shortest position in the NBA is 6’2”, virtually 96% of the US population is eliminated for consideration on height alone.
Another thing that stands out is the weight difference in the NFL compared to other major sports. Every position averages a higher weight than the average US man. A big driver of this is the ‘arms race’ of teams drafting larger and larger offensive linemen and subsequently larger defensive linemen in response. Below is a bar chart displaying the number of players in the NFL that weighted over 300 pounds in ten-year intervals. In 1980, only 3 players weighted over 300 pounds – today average offensive lineman is 6’5” 312 pounds.
