Polling sources

Wikipedia and MediaWiki are used as compiled indexes for many historical tables. Country pages retain original poll links where those links are present in the source table.

Source model

Each country loader targets a defined set of national polling tables, normalises pollster and party names, rejects unrelated table types, and keeps fieldwork dates, samples, results, and source URLs. The country page shows a compiled-source link and links individual pollster names to original reports whenever possible.

Compiled tables are useful, but they can contain errors. A value should be checked against the linked original publication before being quoted as authoritative.

Fallback archives

Country pages include checked local polling data so they still render when the internet source is unavailable. The page labels that state as bundled or fallback data. It does not silently claim that a fallback was fetched live.

Corrections

If a result, date, party label, pollster, or source link looks wrong, include the country, visible value, expected value, and original publication in a correction report. Reproducible corrections are prioritised over broad requests to change an average.
