The main objective of this specialized map is to affect the spatial differentiation of the natural currency in the Central Bohemian Region and Prague. The map provides information from the Demographic Data Database of the Central Bohemian Region and from the population data by city district of Prague.
The central theme of the map is the relationship between the components of natural growth - birth rates and mortality. The typology of municipalities according to the natural currency is represented by a cartogram, which is a comparison of the gross birth rate and mortality rates in the urban areas of Prague and the municipalities of the Central Bohemian region between 2000 and 2017.
