The data in this handbook are presented in the same systematic manner for all countries in order to provide electoral statistics in line with internationally established standards of documentation. The tables are organized in ten parts:
2.1 Dates of National Elections, Referendums, and Coups d'Etat: Table 2.1 provides an overview of the dates of elections to national political institutions, referendums as well as interruptions of the constitutional order by coups d'état since national independence. Where necessary, the dates of indirect elections are indicated by footnotes. The signs xx/xx are used to indicate that no information could be found regarding the exact polling date.
2.2 Electoral Body: Table 2.2 provides a comparative overview of the evolution of the electoral body, and records the data on population size, registered voters, and votes cast. The figures of registered voters and votes cast are drawn from the relevant tables 2.5, 2.6, 2.7, and 2.9. Population data have been generally rounded and their sources are named in a relevant footnote. Where electors have multiple votes, the column for 'votes cast' documents the numbers of 'ballots cast'. A long hyphen (—) indicates that no information was available. All percentages are based on the figures given in the respective columns of this table.
2.3 Abbreviations: The abbreviations and full names of the political parties and alliances that appear in tables 2.6, 2.7, and 2.9 follow an alphabetical order. Party mergers, splinters, or successions are generally indicated in a footnote. As a rule, party names are given in their original language, and the English translation is provided in parentheses. The abbreviations used in the tables are the ones commonly used in the country or in the international reference texts. In the few cases where no abbreviation is mentioned in electoral documents or reference texts, the authors have resorted to party acronyms. These cases are explicitly mentioned in footnotes.
