Stanford (Calif.) University researchers analyzed the correlation between income and mortality, according to Panam Post.
Here are five things to know:
1. The study found 40-year-old men in households with a mean annual income of $256,000 had an average life expectancy of 85 years in 2001. By 2014, the life expectancy increased by 10 weeks.
2. Forty-year-old men in households with a mean annual income of $17,000 had an average life expectancy of 76 years in 2001. By 2014, the life expectancy increased by four weeks.
3. Researchers found income inequality, unemployment and immigrants were moderately linked to shorter lifespans.
4. In the top income quartile, shorter lifespans associated with the uninsured rate. However, in the bottom income quartile, the uninsured rate did not have an association with lifespans.
5. The researchers concluded low-income families would benefit more from opportunities to increase their incomes, as opposed to more access to health insurance.
