visualization is right at the heart of my own work too I teach Global health and I know having the data is not enough I have to show it in ways people both enjoy and understand now I'm going to try something I've never done before animating the data in real space with a bit of technical assistance from the crew so here we go first an AIS for health life expectancy from 25 years to 75 years and down here an AIS for wealth income per person 400$ 4,000 and $40,000 so down here is poor and sick and
up here is Rich and healthy now I'm going to show you the world 200 years ago in 1810 here come all the countries Europe Brown Asia red Middle East Green Africa south of Sahara blue and the America's yellow and the size of the country bubble show the size of the population and in 1810 it was pretty crowded down there wasn't it all countries were sick and poor life expectancy were below 40 in all countries and only UK and the Netherlands were slightly better off but not much and now why start not the world the Industrial
Revolution makes countries in Europe and elsewhere move away from the rest but the colonized countries in Asia and Africa they are stuck down there and eventually the Western countries get healthier and healthier and now we slow down to show the impact of the first world war and the Spanish flu epidemic what a catastrophe and now I speed up through the 1920s and the 1930s and in spite of the Great Depression Western countries forg on towards greater wealth and health Japan and some others try to follow but most countries stay down here now after the tragedies
of the second world war we stop a bit to look at the world in 1948 1948 was a great year the war was over Sweden topped the medal table at the Winter Olympics and I was born but the differences between the country of the world was wider than ever United States was in the front Japan was catching up Brazil was way behind Iran was getting a little richer from oil but still had short lives and the Asian Giants China India Pakistan Bangladesh and Indonesia they were still poor and sick down here but look what is
about to happen here we go again in my lifetime former colonies gained independence and then finally they started to get healthy and healthier and healthier and in the 1970s then countries in Asia and Latin America started to catch up with the Western countries they became the emerging economies some in Africa follows some Africans were stuck in Civil War and others hit by HIV and now we can see the worldall today in the most upto-date statistics most people today live in the middle but there a huge difference at the same time between the best of countries
and the worst of countries and there are also huge inequalities within countries these bubbles show country averages but I can split them take China I can split it into provinces there goes Shanghai it has the same wealth and health as Italy today and there is the poor in L Province gu show it is like Pakistan and if I split it further the rural parts are like Ghana in Africa and yet despite the enormous disparities today we have seen 200 years of remarkable progress that huge historical gap between the west and the rest is now closing
we have become an entirely new converging world and I see a clear Trend into the future with Aid trade Green Technology and peace it's fully possible that everyone can make it to the healthy wealthy Corner well what you have seen in the last few minutes is a story of 200 countries shown over 200 years and Beyond it involved plotting of 120,000 numbers pretty neat HH
