What is the relationship between mortality and income in the US?

In summary, places with higher income inequality tend to have lower average life expectancy. Because places with higher income inequality often have higher poverty rates or lower average incomes, the bivariate correlation partly reflects the concave shape of the relationship between individual income and health.

Why is there a relationship between GNP per capita and life expectancy?

Once an economy enters the demographic transition, the reduction in fertility rates more than compensates the mechanical increase in population so that increases in life expectancy lead to lower rates of population growth.

How does increasing life expectancy affect economy?

In theory, an increase in life expectancy may have positive or negative effects on per capita income.

Do low-income Americans live longer?

Their results suggested that among U.S. men aged 40 years and older, those with the lowest income were expected to live 14.6 years less than men with the highest income. In the case of U.S. women at the same age, life expectancy was 10.1 years shorter for those with the lowest incomes compared with those with the highest incomes.

Why is life expectancy different in different parts of the US?

An influential study published in 2016 in JAMA Network found that there was a significant difference in the life expectancy of people living in different areas of the United States. The difference, the researchers argued, was down to the variation in the populations’ income levels.

What are the main outcomes and measures of life expectancy?

Main outcomes and measures: Relationship between income and life expectancy; trends in life expectancy by income group; geographic variation in life expectancy levels and trends by income group; and factors associated with differences in life expectancy across areas.
