Future Projections of World Population Ranking
1. Estimation of Future Population
I have recently been studying the political structures of Nigeria and India by reading their constitutions.
I chose these countries because they are large countries with large populations and can be classified as English-speaking countries due to their historical backgrounds.
Population estimates are highly reliable, so unless there is a global war or natural disaster, they are one of the data that can be trusted.
2. Treemapping
Recently, I found a website that provides easy-to-understand Bubble Charts of future projections of the world population by country and region.
But I lost track of it and couldn't find it no matter how much I searched.
I thought of making it myself, but it was quite a hassle, so I decided to settle for making Treemapping, which can be easily made with Excel.

3. Postscript
I wanted to make something a little more comprehensive and easy to understand, and while searching for data on the Internet, I happened to find the site with Bubble Charts that I had lost track of.
So, the research is over (´・ω・`)
