*Numbers of countries refer to entire countries; some projects have separate samples for sub-national territories, e.g. East and West Germany. Counting territories instead of countries would bring the total number up to 48.

**Numbers of respondents with coded parties exclude respondents who did not choose a response corresponding to a party name, such as those who did or would not vote, those ineligible to vote, missing values, etc. The total number of respondents in the coded surveys approaches two million.

***Of the three waves of the Life in Transitions Surveys, questions about party preferences are available only in the survey from Greece in Wave 3.
