On a map of the world, Denmark seems but a rather tiny country with its 43.098 square kilometres. In comparison to its size, Denmark has a very long coast line of approx.  7.300 km. The explanation lies in the many large and small named islands, 407 in all.  Only 20% of the area is built on, while the remaining 80% is made up of agricultural areas, forests, dunes, lakes, and bogs.

Approximately 5.4 million people live in Denmark, making it the most densely populated nation in Northern Europe.  Of these 5.4 million inhabitants, 1.1 million live in the metropolitan area.  According to number of inhabitants, the ten largest cities are: 

Copenhagen & Frederiksberg 672.218
Århus 237.551
Odense 158.163
Aalborg 121.818
Esbjerg 70.880
Randers 59.565
Horsens 51.670
Vejle 50.213
Kolding 55.596
Roskilde 45.824
