As people live longer, ages at death are becoming more similar. This dual advance over the last two centuries, a central aim of public health policies, is major achievement modern civilization. Some recent exceptions to joint rise life expectancy and span equality, however, make it difficult determine underlying causes this relationship. Here, we develop unifying framework study equality time, relying on concepts about pace shape aging. We dynamic relationship between with reliable data from...

This article reviews some key strands of demographic research on past trends in human longevity and explores possible future life expectancy at birth. Demographic data age-specific mortality are used to estimate expectancy, validated exceptional spans study the maximum length life. In countries doing best each year, started increase around 1840 a pace almost 2.5 y per decade. trend has continued until present.

People who are more socially integrated or have higher socio-economic status live longer. Recent studies in non-human primates show striking convergences with this human pattern: female social partners, stronger bonds dominance rank all lead longer lives. However, it remains unclear whether environments also predict survival male primates, as does men. This gap persists because, most males disperse among groups, resulting many disappear unknown fate and dates of birth. We present a Bayesian...

Is it possible to slow the rate of ageing, or do biological constraints limit its plasticity? We test 'invariant ageing' hypothesis, which posits that ageing is relatively fixed within species, with a collection 39 human and nonhuman primate datasets across seven genera. first recapitulate, in primates, highly regular relationship between life expectancy lifespan equality seen humans. next demonstrate variation genera orders magnitude smaller than pre-adult age-independent mortality....

Current measures of population health lack indicators capturing the variability in age-at-morbidity onset, an important marker to assess timing patterns individuals' deterioration and evaluate compression morbidity. We provide global, regional, national estimates morbidity onset from 1990 2019 using healthy lifespan inequality (HLI). Using data Global Burden Disease Study 2019, we reconstruct age-at-death distributions calculate (LI), HLI. measure LI HLI with standard deviation. Between...

The Gini coefficient of the life table is a concentration index that provides information on lifespan variation. Originally proposed by economists to measure income and wealth inequalities, it has been widely used in population studies investigate variation ages at death. We focus complement coefficient, Drewnowski's index, which equality. study its mathematical properties analyze how changes over time relate expectancy. Further, we identify threshold age below mortality improvements are...

Abstract When assessing health inequalities, should one compare outcomes across predetermined groups (e.g., race, ethnicity, socioeconomic status), or individuals? Group-based approaches comparing group-specific means do not account for intra-group heterogeneity. Yet, traditional based on additive decompositions splitting total inequality in its within- and between-group components fail to elucidate the groups’ relative performance. Here, we develop a third approach pairwise comparisons...

Empirical research on human mortality and extreme longevity suggests that the risk of death among oldest-old ceases to increase levels off at age 110. The universality this finding remains in dispute because two main reasons: i) high uncertainty around statistical estimates generated from scarce data, ii) lack country-specific comparisons. In article, we estimate patterns above 105 using data International Database Longevity, an exceptionally large recently updated database comprising more...

Demographic thought and practice is largely conditioned by the Lexis diagram, a two-dimensional graphical representation of identity between age, period, birth cohort. This relationship does not account for remaining years life, total length or time death, whose use in demographic research both underrepresented incompletely situated. We describe an these six measures sub-identities diagrams that pertain to this identity. provide application framework measurement late-life morbidity...
