Brazil's eligible voter population has reached approximately 158.8 million people ahead of the general elections in October 2026.
The updated figures provide a critical baseline for political campaigns and the Tribunal Superior Eleitoral (TSE) as they organize the logistics for one of the world's largest democratic exercises. Understanding the distribution of the electorate helps candidates target specific demographics and regions.
Data released in June 2026 indicates that the total number of eligible voters ranges between 158.7 million [1] and 158.8 million [2]. This represents a growth of 1.46% [1] compared to the 2022 election cycle. In absolute terms, this constitutes an increase of 3.5 million voters [2].
The TSE said that the highest proportional increase in eligible voters occurred in the North region [1, 2]. Additionally, there has been a notable rise in the number of Brazilian citizens registered to vote from abroad [1, 2].
Regional biometric registration efforts have also seen significant progress. In the state of Maranhão, where there are 5,192,144 eligible voters [5], 95% of the electorate has completed biometric registration [6]. Similarly, Mato Grosso reported a biometric registration rate of 93.7% [7], which exceeds the national average for the 2026 cycle.
These figures reflect the ongoing effort by the TSE to modernize the voting process and ensure the integrity of the ballot through biometric verification. The stability of the electorate size, with only modest growth, suggests a maturing voting population as the country prepares for the upcoming polls.

The modest growth in Brazil's electorate indicates a period of demographic stability, but the strategic shift toward the North and the diaspora suggests changing political geographies. High biometric registration rates in states like Maranhão and Mato Grosso signal a successful push toward digital security, which may reduce disputes over voter identity during the October 2026 elections.
