Eunomia projects people aged 16 to 35 will make up 39.1% of Argentina’s population aged 16 or older in 2027, a demographic measure that is not a count of voters.
The firm’s October report estimates the group will total 14.43 million people nationwide: 6.63 million ages 16 to 24 and 7.80 million ages 25 to 35. In Buenos Aires Province, Eunomia projects 5.25 million people in the group, or 37.8% of residents aged 16 or older.
Argentina allows citizens by birth or choice to vote starting at age 16. The National Electoral Observatory reports that 1,139,315 people ages 16 and 17 were on the national electoral roll for the 2025 election, representing 3.16% of registered voters. Eunomia’s population estimate also includes foreign residents who cannot vote in national elections; its report cautions that the figures do not represent actual votes and that 16- and 17-year-olds may participate at different rates from older voters.
The provincial projection and municipal figures cover different years and areas. In calculations based on the 2022 census, Eunomia put people ages 16 to 35 at 40.2% of residents age 16 or older across 40 municipalities in the Buenos Aires metropolitan area. The shares ranged from 46.9% in Presidente Perón to 29.5% in Vicente López. Eunomia says it estimated the ages at the edges of the group by assuming an even distribution within census bands for ages 15 to 19 and 35 to 39.
Education and work circumstances also differ across young people. A 2026 study by the Catholic University of Argentina’s Observatory of the Social Debt found that 39.6% of people ages 18 to 25 had not completed secondary school, including those still studying. It found 32.4% were enrolled in or had completed higher education. The study reported that 14.2% of the full age group had a job with full labor rights; its measure includes everyone in that age range, whether employed, unemployed or inactive. The study also associated household socioeconomic position with differences in education and work opportunities.
Argentina’s National Institute of Statistics and Censuses (INDEC) reported that, in the fourth quarter of 2024, 97.8% of people ages 18 to 29 used a mobile phone and 96.5% used the internet in its survey of 31 urban agglomerations. In the Reuters Institute’s 2026 Argentina survey, 19% of respondents ages 18 to 34 said they had used Luzu TV to access news in the previous week.
The population and survey figures describe age, location and social conditions. They do not establish young people’s voting preferences or an advantage for any party or candidate.
