Could Historical Mortality Data Predict Mortality Due to Unexpected Events?

Abstract

Research efforts focused on developing a better understanding of the evolution of mortality over time are considered to be of significant interest—not just to the demographers. Mortality can be expressed with different parameters through multiparametric prediction models. Based on the Beta Gompertz generalized Makeham (BGGM) distribution, this study aims to evaluate and map four of such parameters for 22 countries of the European Union, over the period 1960–2045. The BGGM probabilistic distribution is a multidimensional model, which can predict using the corresponding probabilistic distribution with the following parameters: infant mortality (parameter θ), population aging (parameter ξ), and individual and population mortality due to unexpected exogenous factors/events (parameters κ and λ, respectively). This work focuses on the random risk factor (λ) that can affect the entire population, regardless of age and gender, with increasing mortality depicting developments and trends, both temporally (past–present–future) and spatially (22 countries). Moreover, this study could help policymakers in the field of health provide solutions in terms of mortality. Mathematical models like BGGM can be used to achieve and highlight probable cyclical repetitions of sudden events (such as Covid-19) in different time series for different geographical areas. GIS context is used to map the spatial patterns of this estimated parameter as well as these variations during the examined period for both men and women.

“…It is an exploratory process whereby we attempt to quantify the observed pattern and then explore the processes that may have generated the pattern observed (Gatrell et al, 1996). Spatial analysis refers to quantitative geography and data analysis with quantitative methods and as a result it finds applications in most sciences in which statistical data are analyzed with geographical reference (Faka, 2020;Andreopoulos et al, 2021;Faka et al, 2021Faka et al, , 2022. It is inextricably linked to GIS and geoinformatics, a distinct field of basic and applied research considering spatial data and their impact.…”

“…A respiratory disease outbreak that started in Wuhan, China and expanded to many other nations has affected several countries around the world. The virus responsible for the outbreak, 2019-nCoV, was discovered in late 2019 [1,[1][2][3][4][5]. As the global death toll from COVID-19 grows, more people are becoming aware of the unequal distribution of SARS-COV-2 mortality among vulnerable populations.…”
