It 's interesting to note that the average life of the population is gradually elongated during the twentieth century, to the point that life expectancy a current resident of Valdantena, Pracchiola area has more than doubled compared to his compatriot who lived in the years 1900-1910, ie in a decade, however, not characterized by specific situations, which were, in the late 20s, the first conflict world and, soon after the outbreak of English flu.
It 's true that the study of demography of Valdantena and other towns of the Valley of Magra partially distorted by the gradual expulsion of the younger population, but the age at death in the late nineties of the last century, is attested by the vast majority of cases well beyond the seventieth year of age, frequently exceeding the threshold of 90 years. It should be noted that, throughout the first half of the twentieth century, those who arrived at the age of 90 were rare and that the age reached by those who had escaped to the high infant mortality rate stood between 60 and 70 years.
In the coming time, just after some technical difficulties, and put some tables showing the network - a graph - the data from the study of population in the territory of Valdantena (statistical data drawn from the parish registers re-arranged by Mauro Bertocchi and today carefully preserved in the Diocesan Bishop of Pontremoli by Luigi Farfarana). They are the ones that we now have, data is still provisional, but I would say coming to lead to definitive values, since the differences which currently register are no longer significant percentage. Interestingly, the trend line (the one in red) indicates a gradual climb, unlike the previous century, when the trend in the average age at death results in a nearly horizontal line. At the same time I'm sure if the data are confirmed by analysis documents (State of souls and Book of the Dead) in the surrounding parishes (specifically Pracchiola).
My attention is now an emphasis on certain facts which I believe should be more accurate analysis: mortality attributable to the First and Second World War, the period of English flu, and some epidemiological situations (probably diphtheria) whose effects are really tragic found in the last quarter of the nineteenth century. Another aspect to consider carefully is then the whole phenomenon of migration, both to the Americas that lasted almost until the sixties of the twentieth century, is that towards the industrialized areas of Italy and, in smaller numbers, to other European countries.
