& Dasymetric mapping
The second map had to be a dasymetric map displaying the varying share of foreign-born inhabitants between and within different districts of Malmö.
A dasymetric map is a type of thematic map that uses additional data (e.g. residential districts) within a larger urban area (e.g. Malmö urban locality) to refine the representation of a specific variable (e.g. foreign-born inhabitants) across the geographic area. Similar to, yet unlike a choropleth map, which displays data within predefined boundaries, a dasymetric map redistributes the data based on actual land use or other relevant criteria. This method results in a more accurate representation of the spatial distribution of the variable, as it takes into account the actual density and distribution of the phenomena being mapped rather than assuming equal distribution across the entire predefined boundaries.
Hence, the display of the share of foreign-born was confined to areas where people are actually known/thought to mainly reside.
