Researchers from the CIBERESP and CIBER-ISCIII collaborations investigated the impact of socioeconomic factors on longevity, Scientific Reports noted.

On the basis of processing more than 35 thousand sheets from the census of the population of Spain for 2011-2013, specialists have created special schedules, which displayed a presumptive average life expectancy based on socio-economic factors, such as wealth and region of residence.

According to the scientists' findings, women and men from Spain's poorest areas lived 3.2 and 3.8 years less than their wealthier compatriots from wealthy areas. Women were also found to live on average 5.6 years longer than men (82.9 years for women; 77.3 years for men).

An index developed by the Spanish Society of Epidemiology was used for the graphs. It includes information derived from basic indicators, such as the percentage of manual workers (both employed and unemployed), temporary workers, the percentage of the population without secondary education and the percentage of residence without Internet access.
