“…On the other hand, a regression in infrastructure and services may contribute to population decline. Caution should be exercised in assessing this correlation because the causes of depopulation in many European regions are highly complex and ambiguous (Merino & Prats, 2020;Szymanowski & Latocha, 2021), and may involve various demographic (Westhoek et al, 2006;Coleman & Rowthorn, 2011;Wiest et al, 2011), psychosocial (Paniagua, 2002a;Stockdale, 2002), environmental (Willian & Jobes, 1990;Gare & Arran, 1995), and economic factors (Commins, 1978;Pezzini, 2001;Paniagua, 2002b). One should agree with the statement by E. Gruber et al (2015), however, that changing population sizes as well as changing population structures have produced new patterns of SGI demands and needs with different regional characteristics which are a challenge for public institutions.…”
