This bilingual, English-Czech atlas of Czechoslovakia is one of the first to use statistical data to evaluate spatial aspects of population development over time. Its twelve chapters present various themes relating directly to population from a historical perspective, such as demographic structures and processes, migration, economic structure, cultural structure, social status, crime, and elections. Drawing on census results from 1921 to 2011, including population registers from the postwar years, more than three hundred maps present time series of these basic population statistical indicators from the beginnings of the independent Czechoslovak state up to the present. Uniquely, the atlas shows the development of each indicator over time within a single map sheet through a series of maps with a cohesive legend.
Administrative division. The chapter covers the development of administrative division from the 1920s to the present. It is included to inform readers about basic changes in the system of districts and also touches on the collection and processing of statistical data. Administrative maps are also processed for census years and show the district system for that year, as well as corresponding to the base used by the atlas as a whole. In addition, this chapter includes historical administrative maps in order to show significant changes in the system of districts.
