The Great Escape: how societies increased health, wealth and happiness CENV 110 Trends in human well-being • What constitutes well-being • Basic human necessities – Food – Clothing – Shelter • Other important factors – Health, life expectancy, child mortality – Culture – Leisure time Small groups • List what your group believes would be the three best “measures” of well-being Some examples • • • • • Life expectancy Income Political Freedom Social equality Environmental quality The life of man, solitary, poor, nasty, brutish, and short. Thomas Hobbes The Leviathan The ladder of life and measuring happiness • Imagine a ladder with 11 steps of happiness • Top is “best possible life” • Bottom is “worst possible life” Does money buy health? • Globally richer countries are healthier • But: Chile and Costa Rica have about the same health as the U.S., but spend 12% as much per person Trends in number of poor people Do rich countries get richer? What was responsible for the increase? • By 1850 clean water was generally available so once you reached 40 you had a good life expectancy • Disposal of sewage to prevent the spread of disease (especially diarrhea) • Changes in mortality of children • Note that this was before antibiotics, vaccination • It was due to better nutrition and living conditions and understanding disease transmission • People were skinny and short But it can’t be largely diet • Because rich people did not survive longer until about 1750 • The industrial revolution brought people to cities which were very unhealthy places • Sewage was rampant, pollution was rampant, and clean water hard to find • It is this period 1750-1850 where the health of the wealthy increased while the poor did not Big changes in the mid 19th century John Snow 1813-1858 Founder of modern epidemiology Showed that a cholera outbreak in London was largely coming from a single water pump that was contaminated. This work led to public works to provide clean water and to stop sewage being dumped everywhere. Louis Pasteur Louis Pasteur 1822-1895 Founder of microbiology, invented vaccines for rabies and anthrax Founded the germ theory of disease, pasteurization of milk etc. Ignaz Semmelweis 1818-1865 Austro-Hungarian doctor who showed that childbed fever which killed many women after childbirth was due to disease transmission by doctors. Showed that the use of antiseptics and hand cleaning prevented this disease Why did the rest of the world catch up so fast • It is not complex modern medicine that increases life expectancy so much • It is public health – which is straightforward and generally cheap Changes in average height Changes in height in Japan Men Women Equity Does a rising tied lift all boats? US In the U.S. the rich get richer So what caused the great escape? Health • Scientific knowledge – Importance of clean water – Germ theory of disease • Government action – Public health programs • Better nutrition – Economic development – The green revolution • Less war Wealth • Technological development – Scientific advances – The industrial revolution • Better governance • Increased trade Culture, freedom and welfare • Less despotism • More wealth – more leisure and travel • Improving air and water quality (in some places) • The internet? Study guide • • • • • • • • • Draw a graph where the X axis is GDP (income per person) and the Y axis is peoples rating of their happiness going from 1 to 11. Draw the general relationship from the data presented in class. In the last 30 years which countries have grown their economy the fastest?. Which the slowest? What were the differences or similarities in life expectancy at birth in rich and poor families in England in 1500. Draw the following graph. X axis is calendar year going from 1850 to 2000. Y axis is life expectancy. Scaled from 0 to 80 years. Draw the trend for the U.S. population of life expectancy at birth. Where did it start in 1850 and where is it now? Draw a trend for the life expectancy if you reached 70 years of age? What are the key elements of modern public health? What is the trend in the height of people in the last 50 years and what country now has the tallest people in the world? What is the trend in the proportion of the U.S. population in poverty in the last 40 years What has been the trend in the last 100 years of the proportion of US income obtained by the top 1% income group What are the key factors that have led to increased health and life expectancy around the world in the last 200 years?
