It is more common in colder climates (e.g. at higher northern and southern latitudes); in warmer and tropical regions it is restricted to habitats highly modified by humans (sewers, buildings, ports, etc.). It does not compete with R. rattus, as the latter is scansorial/arboreal whereas R. norvegicus is strictly terrestrial.
