Estimation of life expectancy in small areas using big data from the municipal registry

Given the importance of knowing life expectancy, with less aggregation than provincial level, the paper aims to estimate it for municipal and sub-municipal areas, by means of big data from Registry of Municipal Census Office. The UN approved the 2030 Agenda, with 169 Sustainable Development Goals in 17 domains, placing in SDG 3 (Health and wellbeing) as many as 6 goals for mortality reduction out of 9 total and for improvement of life expectancy at birth and healthy life. We highlight the validity of a tool, such as the real-time mortality observatory, which we have been designing for some years as a support to both medicine and criminal justice, as an alternative to the classic epidemiological analysis and appraisals based on outdated information. For Taranto city, where the environmental pressure is very strong, different statistical sources can be used to shorten these waiting times compared to ecological and epidemiological studies based on official data which have a longer circuit.
