Overseas Voters Now Outnumber Residents in 123 Spanish Towns

Data from the Register of Spaniards Residing Abroad (CERA) as of July 1, 2026, has triggered widespread concern: in 123 Spanish municipalities, registered overseas voters now outnumber actual residents, and in 21 of these, the CERA population is at least double the resident count. This is not merely an administrative detail; it proves that the electoral roll is being legally rewritten, sparking a debate on its political consequences.

The Grandchildren Law and the Madarcos Effect

The most striking case is Madarcos, in Madrid: 54 CERA voters versus 52 in-person voters. In a village of just 50 inhabitants, there are more external voters than internal ones. This phenomenon is attributed to mass naturalizations processed under the Democratic Memory Law, commonly known as the "Grandchildren Law," which allowed descendants of Spaniards to obtain citizenship without ever setting foot in Spain.

General figures, derived from National Statistics Institute (INE) data, reveal an unusual landscape: 451 municipalities have a CERA population equivalent to at least 50% of their residents; 220 reach 75%; 123 have equal or more CERA voters than inhabitants; and 21 see their population doubled by overseas voters. The distribution is uneven, leading some to argue that the government could influence where votes are concentrated, as CERA weight clusters in specific districts.

Legal Fraud or Simple Emigration?

Interpretations vary. One school of thought argues that CERA growth stems from emigration rather than the Grandchildren Law: municipalities losing young people for decades, with elderly residents passing away while former inhabitants maintain their voter registration. In this view, the overseas register reflects rural depopulation, not electoral manipulation.

Opposing voices contend that the issue lies not in the census but in voting power: although overseas turnout is traditionally low, a small percentage of well-distributed votes can decide seats in contested provinces. The precedent set during the July 2023 general elections, when CERA vote counts altered parliamentary math in several provinces, serves as a warning. Fraud, they argue, does not require millions of fake ballots; moving a few hundred votes in tight districts suffices.

Political Consequences: Regionalists and Separatists Hit First

A rarely highlighted fact is that separatist and regionalist parties would be most affected by the new census. The logic is straightforward: overseas votes tend to concentrate on major national options, diluting the influence of territorial formations. If CERA continues to grow, the electoral map of regions like Catalonia or the Basque Country could shift without a single resident changing location.

Meanwhile, the opposition and judiciary remain largely passive. The sense of impunity is so strong that some analysts assume the current government will remain in power regardless. The only certainty is that the 2026 census no longer resembles that of 2016, and the law enabling this change appears irreversible.
