According to the World Health Organization the global life expectancy at birth in 2016 was 72 years.The global average life expectancy rose by 5.5 years between 2000 and 2016 the fastest increase since the 1960s. The researchers analyzed the data which included 7.65 million deaths between 2001 and 2016, taking a close look at where each death occurred and disparities by community noting which communities were the most affluent and which were the most deprived.
The researchers found that life expectancy at birth in 2016 was consistently lower in more deprived communities. Among women life expectancy ranged from 78.8 years in the most deprived areas to 86.7 years in the most affluent areas and among men it ranged from 74 to 83.8.
Additionally although life expectancy increased in most communities from 2001 to 2016 gains were larger in the affluent groups the researchers found.More research is needed to determine the exact contribution of factors driving such inequalities but the researchers noted in the study that the largest contributors to life expectancy inequalities were deaths in children younger than 5 mostly neonatal deaths, respiratory diseases, heart disease, lung and digestive cancers and dementias in older adults.
