Electoral behaviour reflects both the historical development of the state and regional changes in the social structure of the population. For this reason the atlas includes a chapter evaluating the results of parliamentary elections and the significance of constituent parties in a historical perspective.
The first two map sheets give a detailed description of election results for the National Assembly of the Czechoslovak Republic in 1920, the Lower chamber of Parliament in 1990 and the most recent elections to the Chamber of Deputies of the Parliament of the Czech Republic. The following three map sheets show the development of leftist, rightist and religious parties and certain interesting features of electoral geography.
Two partial maps are dedicated to the first direct election of the President of the Czech Republic - to regional differences in electoral turnout and the results of the second round of the presidential election.
