Rosling was born inUppsala, Sweden, on 28 July 1948.^[8] From 1967 to 1974, he studied statistics and medicine atUppsala University, and in 1972 he studied public health atSt. John's Medical College,Bangalore,India. He became a licensed physician in 1976 and from 1979 to 1981 he served as District Medical Officer inNacala in northernMozambique. In 1981, he began investigating an outbreak ofkonzo, aparalytic disease first described in theDemocratic Republic of the Congo.^[9][10][11] His investigations earned him aPh.D. at Uppsala University in 1986.^[11] Rosling wasdyslexic.^[12][13]

Rosling presented the television documentaryThe Joy of Stats, which was broadcast in the United Kingdom byBBC Four in December 2010 and has been made available to 'catch up' on BBC iPlayer since.^[14] He presented a documentaryDon't Panic — The Truth about Population for theThis World series using aMusion 3D projection display,^[15] which appeared onBBC Two in the UK in November 2013.^[16] In 2015 he presented the documentaryDon't Panic: How to End Poverty in 15 Years, which was produced by Wingspan and aired on theBBC just ahead of the announcement of theUN'sSustainable Development Goals.^[17][18]

Rosling was asword swallower, as demonstrated in the final moments of his second talk at theTED conference.^[19] In 2009 he was listed as one of 100 leading global thinkers byForeign Policy,^[20] and in 2011 as one of 100 most creative people in business byFast Company.^[21] In 2011 he was elected member of theSwedish Academy of Engineering Sciences and in 2012 as member of theSwedish Academy of Sciences.^[22] He was included in theTime 100 list of the world's 100 most influential people in 2012.^[23]

Rosling spent two decades studying outbreaks ofkonzo, aparalytic disease, in remote rural areas across Africa and supervised more than ten PhD students.^[24] His work withJulie Cliff, Johannes Mårtensson, Per Lundqvist, and Bo Sörbo found that outbreaks occur among hunger-stricken rural populations in Africa where a diet dominated by insufficiently processedcassava results in simultaneous malnutrition and high dietarycyanide intake.^[11][25][26]

Rosling's research also concerned other links between economic development, agriculture, poverty and health.^[27] He worked as full-time consultant to the Swedish International Development Cooperation Agency (Sida) on primary health care from 1984 to 1990 and then as their consultant on HIV until 1994, traveling often to Sida program countries. He was at this time based at the Maternal and Child Care Department (International) at Uppsala University. He was a health adviser to theWorld Health Organization,UNICEF and several aid agencies. In 1993 he was one of the initiators ofMédecins Sans Frontières in Sweden.^[28] At Karolinska Institutet he was head of the Division of International Health (IHCAR) from 2001 to 2007. As chairman of the Karolinska International Research and Training Committee (1998–2004), he started health research collaborations with universities in Asia, Africa, the Middle East, and Latin America. He started new courses on global health and co-authored a textbook on global health that promotes a fact-based worldview.^[29]

Rosling's son,Ola Rosling, built theTrendalyzer software to animate data compiled by the UN and the World Bank that helped him explain the world with graphics.^[9] Rosling co-founded the Gapminder Foundation together with his son Ola and daughter-in-lawAnna Rosling Rönnlund to develop Trendalyzer to convert international statistics into moving, interactive graphics. The provocative presentations that have resulted have made him famous,^[9] and his lectures using Gapminder graphics to visualize world development have won awards.^[30] The interactive animations are freely available from the Foundation's website.

In March 2007, Google acquired the Trendalyzer software with the intention to scale it up and make it freely available for public statistics. In 2008, Google made available aMotion ChartGoogle Gadget and in 2009 the Public Data Explorer.^[31]

When he was 20, in 1968, doctors told Rosling that there was something wrong with his liver and as a consequence, he stopped drinkingalcohol. Aged 29, with a young family, he had testicular cancer which was successfully treated. In 1989, he was diagnosed withhepatitis C. Over the years this progressed and he developedliver cirrhosis. At the beginning of 2013, he was in the early stages of liver failure. However, at the same time, new hepatitis C drugs were released and he went to Japan to buy the drugs needed to treat the infection. He expressed concerns in the media over the restricted use of the new drugs due to high costs, stating that it is a crime not to give every person with hepatitis C access to the drugs.^[32][33][34]

Rosling was diagnosed withpancreatic cancer in 2016, and died of the disease on 7 February 2017.^[6][35]

Rosling is commonly described as an optimist, though he personally rejected the label. In his posthumous bookFactfulness: Ten Reasons We're Wrong About the World – and Why Things Are Better Than You Think he wrote "The five global risks that concern me most are the risks of a global pandemic, financial collapse, world war, climate change, and extreme poverty."^[43] In summary, he wrote, "People often call me an optimist, because I show them the enormous progress they didn't know about. That makes me angry. I'm not an optimist. That makes me sound naive. I'm a very serious "possibilist". That's something I made up. It means someone who neither hopes without reason, nor fears without reason, someone who constantly resists the overdramatic worldview. As a possibilist, I see all this progress, and it fills me with conviction and hope that further progress is possible. This is not optimistic. It is having a clear and reasonable idea about how things are. It is having a worldview that is constructive and useful."^[43]

In his later years he advocated on behalf of refugees from Syria and partnered with theUnited Nations High Commissioner for Refugees (UNHCR) in this effort.^[44] In his last book he wrote repeatedly about the tragedy of the war in Syria saying: "The Syrian conflict will most likely prove to be the deadliest in the world since the Ethiopian-Eritrean war of 1998 to 2000."^[43]

However, some experts consider Rosling's world-view excessively rose-tinted, or anti-environmental. For instance, inThe One-Sided Worldview of Hans Rosling^[45] Christian Berggren, a Swedish professor of industrial management, argues thatFactfulness, "presents a highly biased sample of statistics as the true perspective on global development, avoids analysis of negative trends, and refrains from discussing difficult issues". Seeing Rosling as more optimist than "possibilist", Berggren remarks that, "Factfulness includes many graphs of 'bad things in decline' and 'good things on the rise' but not a single graph of 'bad things on the rise'." In 2013 inThe Ecologist Robin Maynard reported Rosling as raging against the UN's population projections, and against some ecological objections to development: "I don't give a damn about polar bears! I can live without polar bears."^[46]

Hence, Rosling has been criticized as beingPollyannaist about the global political situation in the face of tragedies such as the long-running conflict in Syria, among others.^[9] His work on population growth has also been criticized byPaul R. Ehrlich, the U.S. biologist and Professor of Population Studies at Stanford University, andAnne H. Ehrlich, associate director of the Center for Conservation Biology at Stanford University, in an article, published online by theMAHB, titled "A Confused Statistician." The Ehrlichs also warn that, while some trends that Rosling cites may indeed be positive, there is the possibility of total collapse of those trends if social and political instabilities occur.^[47]

Max Roser saw this differently, writing in his obituary for Rosling: "In portraits of Rosling, he was too often presented as an "optimist" that tells the world that things will turn out well. This is wrong. What Rosling did was to present the empirical evidence up to the present, and he showed that many vastly underestimate the progress that the world has made in improving living conditions globally. The majority of the world is better off now than at any point in history before. This was his positive message. But he never suggested that this should give anyone any reason to be complacent. He always used his fame to draw attention to the living conditions of the worst off and to denounce the lack of support they were receiving from the large group of people in the world that is living in unprecedented comfort. Hans Rosling's message was never that all is good; the enthusiasm for his work came from the fact that he was always convinced that a better world is possible if we care to work towards it."^[48]
