Population Density 2004
The spatial reference system was provided by the digital working map 1:5,000 (DIGK5) of the Information System Urban and Development (ISU), edition 2003/31/12. This working map contains individual statistical blocks with block numbers. Blocks with more than one use are divided into block segments. The numbering and street limit lines of blocks corresponds to those used by the Berlin State Statistical Agency.
Population density was determined for each statistical block and accordingly for block segments. The size of each statistical block, needed for the calculation of population density, was taken from the ISU Land Use Data Base. Figures for the number of inhabitants were assigned to statistical blocks and block segments according to the ISU spatial reference system.
