when the Spanish large power company Iberduero installed two transformation centers in the municipality. The first motorcar arrived in Alkiza on November 2, 1930. Administrative organization In 1775 the City Council issued a decree that organized the collection of fern, dead leaves, and the like for the livestock beddings from the communal land. In it, the municipality was divided into four neighbourhoods: Azaldegi, Aldapa, Arana Behea and Arana Goikoa. At the time the quotas for the payment of the local doctor were established in 1847, the municipality was divided again into four neighbourhoods: Azaldegi, Aldapa, Arana and Herriburua. In 1884 Aldapa neighbourhood was divided into two: Aldapa and Hernio. Sakamidra neighbourhood was set up in 1940, bringing together several farmhouses from Arana and Azaldegi.

The number of inhabitants reached the minimum in 2000, with only 254. At the beginning of the 21st century, the population of Alquiza was comparable to the one it had when it became a municipality. This has a simple explanation from the point of view of the economic and family structure of the municipality.
