The Healthy Life Years (HLY) indicator, also known as disability-free life expectancy (DFLE) or Sullivan's Index, is a European structural indicator computed by Eurostat. It is one of the summary measures of population health, known as health expectancies, [ 1 ] composite measures of health that combine mortality and morbidity data to represent ...
Life expectancy, more technically called the curtate expected lifetime and denoted ,[ a] is the mean of —that is to say, the expected number of whole years of life remaining, assuming survival to age . [ 149] So, (2) Substituting ( 1) into the sum and simplifying gives the final result [ 150]
This is especially true for Healthy life expectancy, the definition of which criteria may change over time, even within a country. For example, Canada is a country with a fairly high overall life expectancy at 81.63 years; however, this number decreases to 75.5 years for Indigenous people in the country. [ 4 ]
The square of the bubbles is proportional to the country's population based on estimation of the UN. Longevity may refer to especially long-lived members of a population, whereas life expectancy is defined statistically as the average number of years remaining at a given age. For example, a population's life expectancy at birth is the same as ...
Life table. In actuarial science and demography, a life table (also called a mortality table or actuarial table) is a table which shows, for each age, the probability that a person of that age will die before their next birthday ("probability of death "). In other words, it represents the survivorship of people from a certain population. [ 1]
Health expectancy calculated by Sullivan's method is the number of remaining years, at a particular age, that an individual can expect to live in a healthy state. [2] It is computed by subtracting the probable duration of bed disability and inability to perform major activities from the life expectancy. The data for calculation is obtained from ...
The Human Development Index ( HDI) is a statistical composite index of life expectancy, education (mean years of schooling completed and expected years of schooling upon entering the education system ), and per capita income indicators, which is used to rank countries into four tiers of human development. A country scores a higher level of HDI ...
Disability-adjusted life years ( DALYs) are a measure of overall disease burden, expressed as the number of years lost due to ill-health, disability, or early death. It was developed in the 1990s as a way of comparing the overall health and life expectancy of different countries. DALYs have become more common in the field of public health and ...
