Section 4: Open Election Data in Practice: Examples from Latin America Brazil

Election cycle assessed: October 5, 2014 general elections: President, National Congress, state governors and state legislatures.

Data standards: Brazil’s election data has the best use of timestamps compared to other countries in the region. Most data is time-stamped, as well as every website page. Data in many cases is also documented well.

Election management body: Brazil provides user-friendly and detailed information on the officials and staff of its electoral management body, the Tribunal Superior Electoral (TSE). The information includes an interactive organizational/staffing chart with hyperlinks to (and a full list of) the names, positions, individual email addresses and phone numbers of staff.

Voter education – Candidate information and status: Brazil’s “DivulgaCand” platform provides a significant amount of data on each electoral candidate. It provides a user-friendly, interactive way to gain information about each candidate’s platform, status and official documents submitted to the TSE. While the provision of official candidate documents is admirable, they are not analyzable, as they are only provided in scanned image files (PDF). In addition to individual candidate data, complete lists of candidates for all elections are available for download in a non-proprietary, analyzable format (CSV). There is no bulk download for all candidates in all elections, however.

Political party registration: Brazil’s data on political party membership stands out when compared to most countries in Latin America. The TSE provides granular data on all individual current and former party members for each party at the state level. The data can be downloaded in a non-proprietary, analyzable format (CSV). While very few countries provide individual member data at all, Brazil goes a step further by providing a rich set of data on each member. This includes date of registration, voter ID number and geographic location by state, city, electoral zone and electoral section. For former party members, it includes date of and reason for cancellation, as well as the date of renewal/reinstatement for those who have rejoined parties. Each file downloaded is accompanied by documentation that explains the data coding scheme. Brazil’s party membership data meets open election data principles.

Polling stations: Brazil’s polling station data meets most open election data principles. The TSE provides a complete list of all polling stations for bulk download in a non-proprietary format (PDF), but unfortunately it is not analyzable. The list includes several geographic levels, as well as the unique identifier and address of each polling station.

Election results: Brazil provides three different options for obtaining access to election results with different levels of detail and different interactive features. Each of them has different positives and drawbacks when considering open election data principles, as described below.

  • Summary-level results: Brazil’s DivWeb platform provides an interactive way to access election results, but it is not granular data, as it only provides vote totals by race (e.g., national-level elections only have national-level results). The data is available in a non-proprietary format (HTML on webpages), but it is not analyzable. Also, as of December 19, 2014, the platform does not function properly and does not provide results for the October 2014 elections.
  • Primary-level results: Brazil’s Divulga platform provides access to data at a more granular level and can be queried in a variety of ways. The platform also requires proprietary software (Java). Data is provided in HTML tables but can also be downloaded in a non-proprietary, analyzable format (CSV). Polling station-level data can be downloaded, but not in bulk. Instead, it can be downloaded by each candidate in each race (see Figure 2 below).
  • Historical results: Brazil’s Repositório platform provides open election results data back to 1945 available for download in a non-proprietary, analyzable format (CSV). In most cases preliminary and final results are available. The data is more granular in more recent elections. Because file sizes are so large, they are split into groups, but even then it can take a significant time to download for slower internet speeds.
