"The present abode of the Himba covers an extensive area of some 30 000 sq. kilometers in [former] South West Afrca [currently Namibia] and Angola jointly. It stretches for 200 km westwards from Ruacana Falls to just below the escarpment, where it is bounded by the arid semi-desert regions of the Namib. The greater part of the Himba territory falls within the borders of South West Africa [currently Namibia], being about 20 000 sq. km in extent. It is roughly bounded by the Hoarusib River in the south, Owambo in the east, the Namib to the west, with the Kunene River as its northern boundary... Almost 7 000 Himba are living here, with probably only half that figure in the adjacent parts of Angola - an average population density therefore of close to one per three sq. km."
