The document summarizes population density and housing distribution in the city of Malmö, Sweden. It shows the hierarchy of city districts and sub-districts, with populations for each site. Maps show the concentration of housing and population density across the city currently and with an additional 100,000 inhabitants distributed either evenly across sites or concentrated in one large development. Adding that number of people evenly would require building 37 more residential towers like the Turning Torso to house them, while concentrating them all in one existing site would make that site the world's most densely populated area.
