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 World’s largest Islands

a1nr8zgq4mzz.pngAustralia 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.

Deep Learning research by country


Above is a bar chart displaying the number of research papers published each year on Deep Learning. Two trends are noticeable: One, Deep Learning/Artificial Intelligence research is on the rise across all the most advanced nations in the world and, Two, China and the US are far outpacing the nearest competitor countries. There is also an A.I. patent battle underway being waged mostly in Silicon Valley (Apple, Facebook, Google) and Seattle (Amazon, Microsoft). AI2.png
