Donor firms were matched to the Ministry of Finance registry (CNPJ and CNAE) to classify industries, with a focus on public-works activities (construction, water/sewage, and energy). Direct federal payments to firms were extracted from the Office of the Comptroller General’s Transparência portal and aggregated to the candidate level by donor list for 2004–2010 (values converted to 2006 reais). The dataset summarizes totals and counts for all donor firms and for the public-works subset, provides windows for 2004–2006 and 2008–2010, and includes tags for payments executed by DNIT and by ministries led by PT or coalition partners. Additional fields capture electorate size by state and service days as substitute or on leave for seated deputies. This structure allows analysts to study patterns of campaign financing and federal contracting around the 2006 election.
