Population density is the number of inhabitants per square kilometre. For the calculation of population density, the land-area concept (which excludes inland water bodies like lakes or rivers) should be used wherever available. However, in several countries in the European Union (EU), the total area, which includes the area of lakes and rivers, is used because it is the only concept for which data are available.
