The most striking case is Cañizar del Olivar, in Teruel. Of its 112 residents, 15 are under 10, representing 13.39% of the total population. It is the highest percentage among Aragon’s 731 municipalities, according to 2025 population data published by the INE.
CAÑIZAR DEL OLIVAR: 15 CHILDREN AMONG 112 RESIDENTS
The figure is even more striking given the municipality’s size. Cañizar del Olivar is home to seven children under five and eight aged between five and nine, meaning that nearly one in seven residents has not yet turned 10.
Close behind are two municipalities in Zaragoza province with a completely different situation in terms of population size. María de Huerva has 848 children under 10 among 6,592 residents, or 12.86%, while Cuarte de Huerva has 1,973 children among 15,380 residents, or 12.83%.

Outside the three provincial capitals, Cuarte de Huerva stands out in terms of numbers, with 1,973 children under 10, a figure far higher than those of the small municipalities topping the ranking by percentage.
