BARCELONA, Spain, Aug. 27 (Xinhua) -- Around half of Spain's municipalities are seeing declining populations, and many of these are at risk of extinction, according to researchers in Barcelona.
The United Nations has been warning of the phenomenon of urban concentration for some time. Although Spain's population surpassed 48 million for the first time in 2023, in the so-called "Espana vacia (Empty Spain)" regions, over 4,000 Spanish municipalities, about half of the total, have seen falling populations.
