- How many people will there be in the world in 2100 compared to now?
- How many babies are born per woman in different regions of the world?
- What percentage of relevant aged girls are enrolled in primary school worldwide?
- What is the average life expectancy across the world – 50, 60 or 70?
To find the answers to these and many more questions I urge you to watch The Data Lecture by Hans Rosling. He does not present the data as dry figures but relates them strongly to life issues facing real people.
In recent years Hans Rosling has revolutionised data analysis and their presentation related to social statistics. He is widely accepted as an authority. On his website www.Gapminder.org he presents data of the wealth and health of all the nations of the world over many decades. These data are able to be interrogated at will (ie by you) in dynamic graphical form (start with the ‘How to use’ tab) – I warn you it is easy to get hooked if you visit the site!
The Data Lecture
The Data Lecture was delivered at the Overseas Development Institute, London, in October 2015. In it Rosling particularly looks at the world population projections and relates them to such data as referred to in the questions above about education etc. He is an excellent communicator. Be prepared to be fascinated – and shocked. It is about 1½ hours long but is easy and interesting viewing; it could even be viewed during the Christmas holiday.
Enjoy, and be educated!
