[3] As in other towns in Lapland, the Swedish language is dominant at an official level in Jokkmokk in modern times.

[3] Jokkmokk was a transit center for Sami refugees from Norway during World War II, in addition to the centre in Kjesäter.

Influenced by its inland and northerly position, Jokkmokk's variety of a subarctic climate (Dfc) is very cold by Swedish standards.

[5] Combining an elevation of 250 metres (820 ft) with being at the foot of the Scandinavian Mountains, Jokkmokk is both cooled down during the day and experiences temperature inversion during night.

This combination makes it the coldest municipal seat in Sweden in terms of winter temperatures, although some rural localities in Lapland are even colder.
