Throughout my degree so far there is one video that I have seen over and over again across modules that I have studied and it still never ceases to amaze me. In my opinion it is one of the most powerful videos out there to demonstrate the dramatic changes of population growth and its future. Hans Rosling highlights the importance of statistics in showing the correlations of the health and wealth of over 200 countries across a 200+ year period. Within 4 minutes, using statistics he shows the evolution of the World’s correlation between life span and income in an understandable and fun (yes statistics can be fun) way.
Hans Rosling’s 200 countries, 200 years, 4 minutes.
To me this video illustrates how the world we all think we live in is not what we thought it was at all. I particularly found it fascinating to see the huge impacts that events such as first World War had on the development of countries. Many LEDC’s which are presently lacking behind in the animations are still struggling to catch up on the MEDC’s in the top right hand corner. Although Hans says that “everyone can make it to the wealthy corner” there are huge barriers that these developing countries are battling with. Thus, reaching the wealthy corner for some countries is far much more unrealistic compared to others.
Before university I hated the thought of having to do statistics and it was something I was worried about studying when I found out it was in my course. I took Maths A level but never had to do statistics within it so it was a completely new concept for me at University. I had my first statistics module last year in my second semester and I had such a good lecturer that I actually looked forward to each lecture. One fantastic resource we received was that our lecturer recorded our lectures and published it online for us afterwards which meant we were able to go over methods and questions visually after a lecture. This was a brilliant tool and a great alternative to understanding something compared to reading a book or lecture notes. I ended up achieving my highest grade of the year in this module and I am currently taking another statistics module this semester which I am thoroughly enjoying. Statistics and quantitative methods is a fantastic skill to have for future employability and isn’t very common across many courses, so it is great that my course involves so much of it!
I hope you enjoyed the video as much as I did. It would be great to hear your thoughts of this video and opinions as to where you think we will be by 2050.
