In Portugal, the right and civic responsibility to vote start at the age of 18 years and are extended for a lifetime. In 2024, there were over 9.25 million registered voters in the country, with those aged between 50 and 54 years constituting the most numerous group, at 844,100 individuals. The youngest registered voters, between 18 and 19 years of age, formed the least numerous cluster, followed by the group between 80 and 84 years, which reckoned 389,651 registered voters.
Lisbon counted the highest number of voters in Portugal, while France headed abroad
As of December 2024, there were over 9.2 million registered voters in the Portuguese electoral register, with the region of Lisbon gathering the highest number, namely 1.9 million. Porto followed in number of registered voters, while Portalegre’s electoral district was the one with the lowest sum. In total, there were 9.3 million voters residing in the national territory. Registered women, namely 4.8 million in number, were slightly more abundant than men. Many Portuguese citizens residing abroad were registered in the Portuguese electoral register in the same year, with Europe aggregating most of them. France was the foreign country harboring the highest number, more than 409,580. Brazil was placed second, where 281,245 Portuguese nationals resided, while the United Kingdom stayed at the 185,854 benchmark.Â
After an unforeseen political crisis, voters were called to the ballots
In March 2025, the Prime Minister LuÃs Montenegro saw his government crumble after his family business rose alarm around the opposition parties for possible conflicts of interest. This precipitated snap elections, despite most Portuguese believing that these could have been avoided. Even after having voted in previous early elections in 2024, the voters in Portugal mostly intended to vote in 2025, in an elective process that reelected Montenegro to the position of prime minister.
