New research results, published in PNAS, challenge previous findings

of huge differences in life expectancy between high and low-income individuals.

The findings, by Claus Thustrup Kreiner, Torben Heien Nielsen and Benjamin Ly Serena, has been published in Proceedings of the National Academy of Sciences (PNAS).

In real life people don´t necessarily stay poor or stay rich, as assumed in previous research. Claus Thustrup Kreiner, Torben Heien Nielsen and Benjamin Ly Serena develop a new method to take this mobility between income-classes into account providing a more realistic way to calculate life expectancy for people from different walks of society. Their results show that in reality the difference between the lifespan of a rich and a poor person is really not that big.
