What do life expectancy and infant mortality indicate about the quality of life people have in country?

The infant mortality rate (IMR) is the number of deaths of infants under one year per 1,000 live births. This rate is often used as an indicator of the level of health in a country. Life expectancy at birth is also a measure of overall quality of life in a country and summarizes the mortality at all ages.

What do life expectancy indicate about the quality of life in a country?

The term life expectancy at birth refers to the mean number of years a new-born child can expect to live if subjected throughout his or her life to the current mortality conditions.

Why is infant mortality rate a good indicator of quality of life?

Infant mortality rate (IMR) is generally regarded as an important national indicator of health because it is particularly sensitive to general structural factors, like socio-economic development and basic living conditions [1].

What is the relationship between infant mortality and life expectancy?

High infant and early childhood mortality result in lower values of life expectancy at birth than at other ages [4]. It is observed that in such populations, those surviving the hazards of early childhood have a higher life expectancy than infants and the maximum life expectancy occurs not at birth but at a later age.

What does the life expectancy at birth indicates?

Life expectancy at birth reflects the overall mortality level of a population. It summarizes the mortality pattern that prevails across all age groups – children and adolescents, adults and the elderly. Average number of years that a newborn is expected to live if current mortality rates continue to apply.

What does life expectancy and literacy rate indicate about the quality of life?

Whilst we recognise that the relationship between literacy and life expectancy is complex, our report finds that people with low levels of literacy are more likely to live in deprived communities, be financially worse off, and have poorer health – all of which are precursors for shorter life spans.

What does infant mortality rate indicate about a country?

Infant Mortality Rates by State, 2019 One of the Healthy People objectives is to reduce the rate of all infant deaths. In 2019, 15 states met the Healthy People 2030 target of 5.0 infant deaths per 1,000 live births. Geographically, infant mortality rates in 2019 were highest among states in the south.

What does infant mortality indicate?

Infant mortality is the death of an infant before his or her first birthday. The infant mortality rate is the number of infant deaths for every 1,000 live births.

What does infant mortality rate IMR indicate?

Infant mortality rate (IMR) is the number of deaths per 1,000 live births of children under one year of age. The rate for a given region is the number of children dying under one year of age, divided by the number of live births during the year, multiplied by 1,000.

What is the relationship between mortality and life expectancy?

Most changes to age-specific mortality trajectories result in an increase of both measures and therefore in a positive relationship. The only circumstance where life expectancy increases and the proportion of life shared always decreases is when life expectancy increases due to lowering the rate of senescence (b1).

What is infant life expectancy?

Life expectancy at birth is defined as how long, on average, a newborn can expect to live, if current death rates do not change. However, the actual age-specific death rate of any particular birth cohort cannot be known in advance.
