Changes

The population density map shall be combined with the [[Archivo:Europa_Poblacion-mayor-de-65-anos-en-la-Union-Europea_2019_mapa_17830_spa.jpg|''Population over the age of 65 in the European Union'' ]] map, which shows a part of the population that, if infected, has a higher morbidity rate due to the age. This map is clearly different to the population density map. The regions that stand out for having a higher number of people over the age of 65 are those that form the Iberian Atlantic Arc [especially Alentejo, Galicia, Asturias and Castile and León (Castilla y León)], the hinterland of France (especially Poitou-Charentes and Limousin), the north of Italy [more specifically Piedmont (Piemonte), Liguria, Friuli-Venezia-Giulia, Tuscany (Toscana) and Umbria], several regions in eastern Germany [Saxony (Sachsen), Saxony-Anhalt (Sachsen-Anhalt) and Thuringia (Thüringen)], a couple in Greece [Epirus (Épeiros) and the Ionian Islands (Iónia nisiá)] and one in Bulgaria (Northwest). In the case of the Iberian regions, older sex-age pyramids are combined with low demographic densities and a highly dispersed population, making the provision of healthcare for older adults even more challenging.
