About

Plano Político — Consultoria e Análise works on evaluating and building statistical models for political analysis. This site presents part of the consultancy's work, including descriptive metrics on the historical performance of polling institutes in Brazilian presidential and gubernatorial elections, focused on what each pollster reported and how those readings compared to the official result.

For the 2026 elections, we've published our national and state poll aggregator here, and will soon launch a full forecasting model for subscribers.
