Our project Prague suburbs: the dynamics of social environment within the growing metropolis aims to describe and explain the transformations of social environment of peripheral parts of the dynamically growing Czech metropolis from industrialisation until present. Key outcomes of the project include a geodatabase of historical spatial and statistical data for cadastral units of Prague, which were recently published on the project website. The data and layers relate to historical population censuses from 1869 until 1910 and can be downloaded – after registration – here.
