In 2023, the life expectancy at birth for women born in the UK was 82.77 years, compared with 78.82 years for men. By age 65 men had a life expectancy of 18.51 years, compared with 20.96 years for women.

This table contains mortality indicators by sex for Canada and all provinces except Prince Edward Island. These indicators are derived from three-year complete life tables. Mortality indicators derived from single-year life tables are also available (table 13-10-0837). For Prince Edward Island, Yukon, the Northwest Territories and Nunavut, mortality indicators derived from three-year abridged life tables are available (table 13-10-0140).

For most of the world, throughout most of human history, the average life expectancy from birth was around 24. This figure fluctuated greatly depending on the time or region, and was higher than 24 in most individual years, but factors such as pandemics, famines, and conflicts caused regular spikes in mortality and reduced life expectancy. Child mortality The most significant difference between historical mortality rates and modern figures is that child and infant mortality was so high in pre-industrial times; before the introduction of vaccination, water treatment, and other medical knowledge or technologies, women would have around seven children throughout their lifetime, but around half of these would not make it to adulthood. Accurate, historical figures for infant mortality are difficult to ascertain, as it was so prevalent, it took place in the home, and was rarely recorded in censuses; however, figures from this source suggest that the rate was around 300 deaths per 1,000 live births in some years, meaning that almost one in three infants did not make it to their first birthday in certain periods. For those who survived to adolescence, they could expect to live into their forties or fifties on average. Modern figures It was not until the eradication of plague and improvements in housing and infrastructure in recent centuries where life expectancy began to rise in some parts of Europe, before industrialization and medical advances led to the onset of the demographic transition across the world. Today, global life expectancy from birth is roughly three times higher than in pre-industrial times, at almost 73 years. It is higher still in more demographically and economically developed countries; life expectancy is over 82 years in the three European countries shown, and over 84 in Japan. For the least developed countries, mostly found in Sub-Saharan Africa, life expectancy from birth can be as low as 53 years.

In 2024, the average life expectancy for those born in more developed countries was 76 years for men and 82 years for women. On the other hand, the respective numbers for men and women born in the least developed countries were 64 and 69 years. Improved health care has lead to higher life expectancy Life expectancy is the measure of how long a person is expected to live. Life expectancy varies worldwide and involves many factors such as diet, gender, and environment. As medical care has improved over the years, life expectancy has increased worldwide. Introduction to health care such as vaccines has significantly improved the lives of millions of people worldwide. The average worldwide life expectancy at birth has steadily increased since 2007, but dropped during the COVID-19 pandemic in 2020 and 2021. Life expectancy worldwide More developed countries tend to have higher life expectancies, for a multitude of reasons. Health care infrastructure and quality of life tend to be higher in more developed countries, as is access to clean water and food. Africa was the continent that had the lowest life expectancy for both men and women in 2023, while Oceania had the highest for men and Europe and Oceania had the highest for women.

Life expectancy is the number of years a person would be expected to live, starting from birth (for life expectancy at birth) or at age 65 (for life expectancy at age 65), on the basis of the mortality statistics for a given observation period. Life expectancy is a widely used indicator of the health of a population. Life expectancy measures quantity rather than quality of life.

BackgroundWhile combination antiretroviral therapy (cART) has significantly improved survival times for persons diagnosed with HIV, estimation of life expectancy (LE) for this cohort remains a challenge, as mortality rates are a function of both time since diagnosis and age, and mortality rates for the oldest age groups may not be available.MethodsA validated case-finding algorithm for HIV was used to update the cohort of HIV-positive adults who had entered care in Ontario, Canada as of 2012. The Chiang II abridged life table algorithm was modified to use mortality rates stratified by time since entering the cohort and to include various methods for extrapolation of the excess HIV mortality rates to older age groups.ResultsAs of 2012, there were approximately 15,000 adults in care for HIV in Ontario. The crude all-cause mortality rate declined from 2.6% (95%CI 2.3, 2.9) per year in 2000 to 1.3% (1.2, 1.5) in 2012. Mortality rates were elevated for the first year of care compared to subsequent years (rate ratio of 2.6 (95% CI 2.3, 3.1)). LE for a 20-year old living in Ontario was 62 years (expected age at death is 82), while LE for a 20-year old with HIV was estimated to be reduced to 47 years, for a loss of 15 years of life. Ignoring the higher mortality rates among new cases introduced a modest bias of 1.5 additional years of life lost. In comparison, using 55+ as the open-ended age group was a major source of bias, adding 11 years to the calculated LE.ConclusionsUse of age limits less than the expected age at death for the open-ended age group significantly overstates the estimated LE and is not recommended. The Chiang II method easily accommodated input of stratified mortality rates and extrapolation of excess mortality rates.

Over the past 75 years, women have generally had a higher life expectancy than men by around 4-6 years. Reasons for this difference include higher susceptibility to childhood diseases among males; higher rates of accidental deaths, conflict-related deaths, and suicide among adult men; and higher prevalence of unhealthy lifestyle habits and chronic illnesses, as well as higher susceptibility to chronic diseases among men. Therefore, men not only have lower life expectancy than women overall, but also throughout each stage of life. Throughout the given period, there were notable dips in life expectancy for both sexes, including a roughly four year drop in 1960 due to China's so-called Great Leap Forward, and a 1.8 year drop due to the Covid-19 pandemic in 2021. Across the world, differences in life expectancy can vary between the sexes by large margins. In countries such as the Nordics, for example, the difference is low due to high-quality healthcare systems and access, as well as high quality diets and lifestyles. In Eastern Europe, however, the difference is over 10 years in Russia and Ukraine due to the war, although the differences were already very pronounced in this region before 2022, in large part driven by unhealthier lifestyles among men.

Distribution of key explanatory variables.

Background: Osteoarthritis and cardiovascular disease (CVD) are prevalent in India. However, there is dearth of literature among Indians studying the relationship between the two. This study was carried out to assess various cardiovascular (CV) risk factors in patients with knee osteoarthritis (OA) with an objective to investigate their association, screening and management.

Methods: In total, 225 patients were included in this cross-sectional study. Participants were diagnosed with knee OA on the basis of Kellgren and Lawrence (K-L) classification of their radiograph. Participants were also assessed for CV risk factors (age, BMI, systolic BP, diabetes mellitus, total cholesterol, HDL, smoking) with the help of the Joint British Society QRisk3 calculator (JBS3), which gave three variables: JBS3 risk score, heart age, life expectancy. Chi Square and Anova p test were used to compare the variables. Pearson’s correlation coefficient was used to find out the relationship between CV risk factors and knee OA.

Results: Patients with severe knee OA had a statistically significant higher prevalence of CV risk factors (p<0.05>. Some patients were diagnosed with hypertension or hypercholesterolemia for the first time and few were aware of the severity of their known co-morbidities. Grade 4 knee OA patients were found to have a mean JBS3 risk of 38%, heart age of 82 years and life expectancy of 77 years as compared to grade 2 patients who had a mean JBS3 risk of 11%, heart age of 63 years and life expectancy of 82 years.

Conclusions: Our study concluded that there is a strong positive correlation between knee OA and CVD with CV risk score being directly proportional to the severity of OA. JBS3 is a comprehensive risk score calculator as well as a screening tool, which produces three more comprehensive variables, namely 10-years risk of developing CVD, physiological heart age and life expectancy.

Methods In total, 225 patients were included in this cross-sectional study. Participants were diagnosed with knee OA on the basis of Kellgren and Lawrence (K-L) classification of their radiograph. Participants were also assessed for CV risk factors (age, BMI, systolic BP, diabetes mellitus, total cholesterol, HDL, smoking) with the help of the Joint British Society QRisk3 calculator (JBS3), which gave three variables: JBS3 risk score, heart age, life expectancy. The data was uploaded to each patient specific file in the mobile based application of JBS 3 risk score calculator and also the excel spreadsheet as raw data. the data has been organised in the spreadsheet.

Later, the data was analysed using SPSS version 20. Chi Square and Anova p test were used to compare the variables. Pearson’s correlation coefficient was used to find out the relationship between CV risk factors and knee OA.

In 2022, life expectancy at birth in Belgium reached 81.69 years. However, life expectancy was subject to gender disparity. In 2022, Belgian women had a life expectancy at birth of 83.78 years, whereas men had a life expectancy of 79.55 years. Life expectancy also differed from one country to another. For instance, in 2020, a Frenchman could at birth expect to live up to 79.2 years and a Dutch person up to 82 years. With that being said, the Belgian life expectancy at birth correlates with western European figures in 2020.

An unclear measure

In 2020, worldwide human life expectancy at birth was of 70 years for men and 75 years for women. However, comparing life expectancy between several countries can be tricky. Indeed, one country could have a rather high life expectancy at birth when another could have a rather low expectancy. Considering the median and mode are therefore crucial.

Life expectancy is commonly confused with the average age an adult could expect to live. This confusion may create the expectation that an adult would be unlikely to exceed an average life expectancy. Yet this statistical measure is based on probability. At every age, life expectancy compares the number of survivors who share the same age. In this sense, life expectancy increases with age as the individual survives the higher mortality rates. In order to compare an age cohort with its corresponding mortality rates, deaths and births need to be acutely registered.

The evolution of life expectancy

Such lists of deaths and births only started to appear in the 19th century. In old times, it can be assumed that life expectancy was fairly low. However, these times were also characterized by very high childhood mortality. It is, therefore, crucial to consider this when comparing life expectancy throughout history. When looking at life expectancy at age 10 in these times, figures are not as low as birth numbers can make you believe. Nowadays, paleodemographist can perform skeletal analysis and genetic analysis to better understand the evolution of life expectancy.

Nonetheless, an adult who has already avoided many statistical causes of mortality should expect to outlive the average life expectancy calculated from birth. Furthermore, life expectancy has undoubtedly risen hand in hand with the evolution of hygiene, technology, medicine, and living standards in general.

Cystic fibrosis (CF) is the one of the most common inherited diseases. It affects around 10,000 people in the UK, and the median survival age is 47. Recent developments making use of longitudinal patient registry data are producing more detailed and relevant information about predicted life expectancy in CF based on current age and clinical measurements. The objective of this study was toconduct an online survey of adults with CF living in the UK using a web-based questionnaire to investigate: (i) if and how they access information on life expectancy; (ii) what they use it for; (iii) if they want more personalised information on life expectancy or the time until other milestones. The survey was advertised through the Cystic Fibrosis Trust using social media. There were 85 respondents, covering men (39%) and women (61%) aged 16–65. 75% had received information on life expectancy either from their CF care team (34%) or other sources (71%), the most common being the Cystic Fibrosis Trust website and research literature. Most people who received information found it to be beneficial and reported using it in a variety of ways, including to plan strategies for maintaining as best health as possible and to psychologically manage current health status. 82% of respondents were interested in more personalised information about their life expectancy, and participants also noted interest in other outcomes, including time to needing transplant or reaching a low level of lung function. Themes arising in text responses included the importance of good communication of information, the difficulty of relating general information to one’s own circumstances, and a desire for increased information on factors that impact on survival in CF. As an outcome from this work, research is underway to establish how information on life expectancy can be presented to people with CF in an accessible way.

Life expectancy in the Netherlands was just under forty in the year 1850, and over the course of the next 170 years, it is expected to have increased to more than 82 in 2020. Although life expectancy has generally increased throughout the Netherlands' history, there were several times where the rate deviated from its previous trajectory. The most noticeable changes were a result of the Spanish Flu pandemic of the late-1910s, and the Second World War.

In 1875, the average person born in Chile could expect to live to the age of 32 years, a figure that would remain largely stagnante throughout the late 19th and early 20th century, as the country’s Parliamentary era would see relatively little change in the day to day lives of the country’s citizens. Outside of two dips in 1910 and 1920, the latter primarily driven by the 1918 Spanish Flu epidemic. Life expectancy would see two sharp increases following the end of the First World War; the first in the 1920s, and the most dramatic in the early 1950s.

The first of these spikes, under President Ibáñez del Campo, can be attributed primarily to large increases in spending on public healthcare and improvements in public sanitation by the Campo administration. The second and larger spike, under President González Videla, can be attributed to a combination of mass immunization and vaccination, and the implementation of a national health care system, drastically cutting child mortality in the country. As a result of these reforms, life expectancy in Chile would more than double in just thirty years, rising from just over 33 years in 1925 to 69 years by 1955. Following the end of the Videla administration in 1952, life expectancy would continue to rise in Chile, as increasing urbanization, and the successful eradication of many childhood diseases would see both child and overall mortality decline. This rise has continued even into the 21st century, and as a result, life expectancy in Chile rose to over 78 years by the end of the century, and in 2020, it is estimated that the average person born in Chile will live to over 82 years old, the highest in South America.
