Social group density is one family per square kilometer in farmland, but may vary between 0.2-5 families per square kilometer in the suburbs. Fox density in mountainous rural areas of Switzerland is three foxes per square kilometer. 0.17 foxes per square kilometer has been recorded in the grassland/semi desert steppe of Mongolia. In northern boreal forests and Arctic tundra, they occur at densities of 0.1 foxes per square kilometer, and in southern Ontario, Canada at 1 fox per square kilometer. The average social group density in the Swiss mountains is 0.37 families per square kilometer.
