If rates are falling, as has been the case over the past decades in OECD countries, actual life spans will be higher than life expectancy calculated using current death rates. As of 2015-2020, Hong Kong has highest life expectancy at 84.63 years. Oeppen and Vaupel (2002) – Broken Limits to Life Expectancy. The average life expectancy is higher in Australia due to a combination of factors that include medical advances as well as effective measures by the government to promote healthier diets and lifestyles. This entry can be cited as: Our World in Data is free and accessible for everyone. As of 2019, life expectancy at birth in Hong Kong was 84.86 years. The Economic History Review, Volume 51, Issue 1 February 1998 Pages 84-112. James C. Riley (2005) – Estimates of Regional and Global Life Expectancy, 1800–2001. The life expectancy for Cyprus in 2018 was 80.75 years, a 0.21% increase from 2017. In 1950 newborns had the chance of a longer life if they were lucky enough to be born in the right place. The life expectancy in 2019 was estimated to be 78.85 years. Top three positions are occupied by Asian nations as Japan and Macao SAR is at 2nd and 3rd position, resp. Research suggests that a healthy diet and a laid-back lifestyle are the major reasons why people in Italy, and especially in the smaller villages, are living longer. This is true for countries around the world. The table below cites life expectancy per country from The World Bank's 2019 statistics. This led to a very high inequality in how health was distributed across the world. the number of people aged 10-15 alive on 1 July 2015). life expectancy at birth equal to 70 years in 2015. The country-by-country estimates for 1800 come with a considerable uncertainty and to not give a false sense of certainty I have not added these estimates into the map, but the estimates for life expectancies are considerably lower than 40 years – as is also shown for the regional and global estimates so that it is safe to assume that showing a life expectancy of less than 40 years on the map is correct. The Journal of Economic History, 79(4), 1129-1153. doi:10.1017/S0022050719000573. As prior visualizations in this entry have shown, life expectancy has been rising globally. As such, infant mortality rate is a key determinant factor. Fogel (2004) – The Escape from Hunger and Premature Death, 1700–2100: Europe, America, and the Third World. This pattern is similar to that observed between life expectancy and per capita income. In every country the life expectancy of women is higher than the life expectancy of men as this chart shows. The cohort life expectancy is the average life length of a particular cohort – a group of individuals born in a given year. Most of these records were set in the US, Japan and a few European countries. By 2016, life expectancy for these comparable countries rebounded to pre-2015 numbers, but in the U.S., such a bounce back did not occur. A century later, life expectancy in India has almost tripled and in South Korea it has almost quadrupled. The researchers found that the decline in life expectancy at birth was even starker for minority populations. While some countries (mostly in Africa) are lacking behind. Life expectancy is the key metric for assessing population health. The 2020 figures represent the lowest life expectancy in the country since 2003, and the largest decline in 40 years, according to Science Daily. But elsewhere a newborn could only expect to live around 30 years. Life Expectancy of Orphans Dying of a Broken Heart WORLD HEALTH RANKINGS OLIVE OIL, HEART DISEASE And The GREEKS Exercise Calorie Calculator SIT LESS AND LIVE LONGER! The US is an outlier that achieves only a comparatively short life expectancy considering the fact that the country has by far the highest health expenditure of any country in the world. However, the actual age-specific death rate of any particular birth cohort cannot be known in advance. You can switch to the map view to compare life expectancy across countries. When we can track a group of people born in a particular year, many decades ago, and observe the exact date in which each one of them died then we can calculate this cohort’s life expectancy by simply calculating the average of the ages of all members when they died. The life expectancy for U.S. in 2020 was 78.93 years, a 0.08% increase from 2019. In the countries with the worst health life expectancy is between 50 and 60 years. Once past childhood, people would be expected to enjoy the same length of life as they did centuries ago. With the seventh-highest life expectancy of any country, Italians can expect to live 83.568 years on average. The average number of years of life expected by a hypothetical cohort of individuals who would be subject during all their lives to the … After analyzing life expectancy data from the World Health Organization's World Health Statistics 2019 report and total population data for each country from the United Nations' World Population Prospects 2019 report, Stacker ranked each country by life expectancy. However, the actual age-specific death rate of any particular birth cohort cannot be known in advance. But if life expectancies are increasing the reality for a cohort born then is that the cohort life expectancy is higher than that period life expectancy. Experts believe that the Korean diet is a big contributing factor to the extended lifespan of the country’s citizens. It tells us the average age of death in a population. Once we have estimates of the fraction of people dying across age intervals, it is simple to calculate a ‘life table’ showing the evolving probabilities of survival and the corresponding life expectancies by age. An important point to bear in mind when interpreting life expectancy estimates is that very few people will die at precisely the age indicated by life expectancy, even if mortality patterns stay constant. The usual retirement period, is often not more than 10-15 years instead. Access to Health Care Life expectancy at birth is also a measure of overall quality of life in a … Life expectancy: 82.5 years. The three maps summarize the global history of life expectancy over the last two centuries: Back in 1800 a newborn baby could only expect a short life, no matter where in the world it was born. In this chart we see the breakdown of deaths by age bracket. In the event of a tie, countries with lower under-five mortality rates were favored. Indeed, this is a common source of confusion in the interpretation of life expectancy figures: It is perfectly possible that a given population has a low life expectancy at birth, and yet has a large proportion of old people. As of 2019, life expectancy at birth in Hong Kong was 84.86 years. doi:10.2307/2173509. Fogel, R W (1986), “Nutrition and the Decline in Mortality since 1700: Some Preliminary Findings”, in S L Engerman and R E Gallman (eds. Population and Development Review. In Science, 296, 5570, 1029–1031. In Science, 296, 5570, 1029–1031. Earlier in this entry we explored the breakdown of total life expectancy between ‘healthy life expectancy’ and ‘years lived with disability or disease burden’. Globally the life expectancy increased from an average of 29 to 73 years in 2019. And if you are wondering where the U.S. ranks, the answer is No. Of the 107 countries with low levels of mortality in 1994 for which the target for life expectancy at birth was set at 75 years in 2015, almost half You have the permission to use, distribute, and reproduce these in any medium, provided the source and authors are credited. Period life expectancy figures can be obtained from ‘period life tables’ (i.e. The increase was largely because of decreases … Bodenhorn, Guinnane, and Mroz (2014) criticized Fogel’s empirical basis and refute the strong claims by Fogel, while the recent publication by Komlos and A’Hearn (2019) that focuses on the US criticizes their work in turn. The population of the Central African Republic has the lowest life expectancy in 2019 with 53 years. Healthy life expectancy has increased across the world (in some countries, significantly in recent decades). Here is an example of a life table from the US, and this tutorial from MEASURE Evaluation explains how life tables are constructed, step by step (see Section 3.2 ‘The Fergany Method’). The visualization shows the life expectancy in England and Wales over the last three centuries. In this definitive guide, we explore all the latest lifespan statistics by state, gender, ethnicity and … Education has played a vital role in extending the average person's life expectancy in Canada but, while medical advances mean that the elderly are living longer, drug addiction is claiming more and more lives among the youth. Why is life expectancy in the US lower than in other rich countries? The life expectancy for U.S. in 2019 was 78.87 years, a 0.08% increase from 2018. Life expectancy improved in 2019. Life expectancy has increased at all ages. There have also been important health innovations whose effect has been mainly in poor countries: for example, the development of freeze-dried serums that can be transported without refrigeration, and of oral rehydration therapy for preventing the death of children from diarrhea.”. As it can be seen, countries with higher expenditure on healthcare per person tend to have a higher life expectancy. In 1950 the life expectancy for newborns was already over 60 years in Europe, North America, Oceania, Japan and parts of South America. It is true that there has been an increase for most countries in both aspects. This can change a country’s estimates by a fraction of a year. Because of this, period life expectancy figures are usually different to cohort life expectancy figures. How long you live could depend on where you stay. It is interesting to see that in 1995 China achieved already relatively good health outcomes at comparatively low levels of health spending. Countries and regions by life expectancy at birth in 2018 (2019 report) Rank Countries and regions Life expectancy at birth (in years) Overall Female Male Difference (years) 1 Hong Kong: 84.7 87.6 81.8 5.8 2 Japan: 84.5 87.5 81.1 6.4 3 Singapore: 83.8 85.8 81.5 4.3 4 Italy: 83.6 85.5 81.7 3.8 5 Spain: 83.4 86.1 80.7 5.4 Switzerland: 83.4 Why do women live longer than men? The life expectancy in some states has fallen in recent years; for example, Maine's life expectancy in 2010 was 79.1 years, and in 2018 it was 78.7 years. until the age of 73.6), provided that mortality patterns observed in 2005 remained constant throughout their lifetime. The term “life expectancy” refers to the number of years a person can expect to live. The map and table below cites life expectancy per country from The World Bank's 2015 statistics. United Nations projections are also included through the year 2100. ( 1 ) United Nations Population Division. List of South American countries by life expectancy Last updated December 05, 2020. The population of the Central African Republic has the lowest life expectancy in 2019 with 53 years. Let’s consider the map showing life expectancy—specifically period life expectancy—at birth in 2005. The latest data on life expectancy in England and Wales can be found at the Office for National Statistics here. Online here. Since then life expectancy doubled in all world regions. This is shown by the yellow line. It is helpful therefore to read our entries on all the many causes of death, from infectious diseases like smallpox and malaria to non-communicable diseases like cancer. No claims are made regarding the accuracy of Life expectancy at birth - male (years) information contained here. If rates are falling, as has been the case over the past decades in OECD countries, actual life spans will be higher than life expectancy calculated using current death rates. This statistic shows the average life expectancy in Europe, by gender and region. by Esteban Ortiz-Ospina. The methodology used to calculate life expectancy can vary slightly between countries. The average life expectancy in Western Europe was 79 years for males and 84 years for females in 2019. ( 1 ) United Nations Population Division. How strong is the link between healthcare expenditure and life expectancy? As can be seen in the chart, inequality in health outcomes has fallen strongly within many countries. First published in 2013; last revised in October 2019. Country Life Expectancy (both sexes) Females Life Expectancy Males Life Expectancy; 1: Hong Kong: 85.29: 88.17: 82.38: 2: Japan: 85.03: 88.09: 81.91: 3: Macao: 84.68: 87.62: 81.73: 4: Switzerland: 84.25: 86.02: 82.42: 5: Singapore: 84.07: 86.15: 82.06: 6: Italy: 84.01: 85.97: 81.90: 7: Spain: 83.99: 86.68: 81.27: 8: Australia: 83.94: 85.80: 82.08: 9: Channel Islands: 83.60: 85.31: … Finally, another point to bear in mind is that period and cohort life expectancy estimates are statistical measures, and they do not take into account any person-specific factors such as lifestyle choices. The solid horizontal line represents the results of the linear regression on all these points; remarkably, the maximum life expectancy seems to follow this linear trend very closely. No claims are made regarding the accuracy of Life expectancy at birth - male (years) information contained here. This map shows the share of the population that is expected to survive to the age of 65. In contrast to the United States, China’s life expectancy is expected to increase over the next decades drastically. Here we see a positive correlation whereby countries with higher healthcare expenditure tend to live more years with disability or disease burden. The seminal reference introducing this method is Fergany (1971) “On the Human Survivorship Function and Life Table Construction,” Demography8(3):331-334). The researchers found that the decline in life expectancy at birth was even starker for minority populations. Mortality in England began to decline in the wake of the Enlightenment, directly through the application to health of new ideas about personal health and public administration, and indirectly through increased productivity that permitted (albeit with some terrible reversals) better levels of living, better nutrition, better housing and better sanitation. And looking at the change over time, we see that as countries spend more on health, life expectancy of the population increases. Twice as long – life expectancy around the world, Life expectancy increased in all countries of the world, It is not only about child mortality – life expectancy by age. Meanwhile, a UK-focused study from Oxford University looking at the average life expectancy in 2020 found men have lost 1.2 years of lifespan since 2019, compared to just 0.9 years for women. It’s often argued that life expectancy across the world has only increased because child mortality has fallen. the number of people aged 10-15 who died in the year 2005), and dividing by the total observed (or projected) population alive at a given point within that interval (e.g. According to recent data by the World Health Organization, the global average life expectancy is 72 years, but this number can be notably higher, or lower, per country. In contrast to the United States, China’s life expectancy is expected to increase over the next decades drastically. Many aspects had to change for life expectancy to double. A high Gini coefficient here means a very unequal distribution of years of life – that is, large within-country inequalities of the number of years that people live. And this progress was not achieved in a few places. By 2016, life expectancy for these comparable countries rebounded to pre-2015 numbers, but in the U.S., such a bounce back did not occur. Over the last decades this global inequality decreased. The evidence that we have for population health before modern times suggest that around a quarter of all infants died in the first year of life and almost half died before they reached the end of puberty (see here) and there was no trend for life expectancy before the modern improvement in health: In the centuries preceding this chart, life expectancy fluctuated between 30 and 40 years with no marked increase ever. World Population Prospects: 2019 Revision, or derived from male and female life expectancy at birth from sources such as: ( 2 ) Census reports and other statistical publications from national statistical offices, ( 3 ) Eurostat: Demographic Statistics, ( 4 ) United Nations Statistical Division. A second striking feature of this visualization is the big decline of life expectancy in 1918. But many of the former developing countries have caught up and we achieved a dramatic reduction of global health inequality. In the early 19th century, life expectancy started to increase in the early industrialized countries while it stayed low in the rest of the world. If this were true, this would mean that we’ve become much better at preventing young children from dying, but have achieved nothing to improve the survival of older children, adolescents and adults. Adding to this are advances in the health-care system as well as access to health care programs. In the countries with the worst health life expectancy is between 50 and 60 years. It is also true that improved healthcare and treatments have also increased the number of years, on average, in which people live with a given disease burden or disability. It is of course not possible to know this metric before all members of the cohort have died. On the y-axis you see the life expectancy of each country. The countries are ordered along the x-axis ascending by the life expectancy of the population. Population Studies. In 1950 it is 2,72 billion. Online here: https://www.aeaweb.org/articles.php?doi=10.1257/jep.20.3.97. In the countries with the worst health life expectancy is between 50 and 60 years. This means the proportional highest gains are achieved in poor countries with low baseline levels of spending. On the very right you see that in 1800 no country had a life expectancy above 40 (Belgium had the highest life expectancy with just 40 years). Our World In Data is a project of the Global Change Data Lab, a registered charity in England and Wales (Charity Number 1186433). The three maps show the global history of life expectancy over the last two centuries.1. Russians in the North Caucasian Federal District that were born in 2019 had the highest average life expectancy among other areas of the country, exceeding 76.6 years. Now, let’s look at the change since 1950. Life expectancy at birth doubled from around 40 years to more than 81 years.8 This achievement was not limited to England and Wales; since the late 19th century life expectancy doubled across all regions of the world. The world map shows the latest data published by the United Nations for life expectancy. It is a logarithmic relationship: the difference in life expectancy per difference in GDP per capita is higher for poorer than for richer countries. In 2019 the life expectancy in Spain, Switzerland, Italy, and Australia was over 83 years. The top 5 countries also includes Japan, Macau, Switzerland, and Singapore. According to the famous research by historian and Nobel laureate Robert Fogel living conditions for most people declined during the early period of industrialization. With the seventh-highest life expectancy of any country, Italians can expect to live 83.568 years on average. Since period life expectancy estimates are ubiquitous in research and public debate, it is helpful to use an example to flesh out the concept. This visualization shows the dramatic increase in life expectancy over the last few centuries as a line chart. The population of many of the richest countries in the world have life expectancies of over 80 years. In these cases, the resulting life expectancy estimates cannot be simply classified into the ‘period’ or ‘cohort’ categories. Residents in the Acciaroli village, for example, eat loads of fresh fish and vegetables and have very little stress. Notice that the relationship in this chart seems to follow a pattern of ‘diminishing returns’: the increase in life expectancy associated with an increase in healthcare expenditure decreases as expenditure increases. One of the most important inputs to health is healthcare. Life expectancy at birth is defined as how long, on average, a newborn can expect to live, if current death rates do not change. If economic development was the only determinant of health countries then we would see a steady relationship between the two metrics and the curve would not shift over time. life tables that rely on age-specific mortality rates observed from deaths among individuals of different age groups at a fixed point in time). The country also ensures that the elderly is cared for properly while also taking measures to tackle childhood obesity, which all contributes towards a higher average life expectancy. How to read the following graph: On the x-axis you find the cumulative share of the world population. The usual retirement period, is often not more than 10-15 years instead. In practical terms, estimating life expectancy entails predicting the probability of surviving successive years of life, based on observed age-specific mortality rates. The life expectancy for Cyprus in 2019 was 80.90 years, a 0.19% increase from 2018. (2019). Data for 1800 is scarce and when not available for a particular country data for 1820 was used. To make comparisons possible they all use the same legend and the researchers that reconstructed the historical data have applied today’s country borders when reporting the health of the past populations around the world. Below we are looking at several aspects, but this section is not yet complete and we will work on it in the future. A possible explanation for this changing relationship is that scientific understanding and technological progress makes some very efficient public health interventions – such as vaccinations, hygiene measures, oral rehydration therapy, and public health measures – cheaper and brings these more and more into the reach of populations with lower and lower incomes.
