In general, Nigerian Pidgin is used to the same extent by all gender groups. However, certain traditionally (but more recently less) male-dominated sectors of the population such as police, soldiers and university students, have led the way in the spread of the language both in Nigeria as well as throughout West Africa. Nonetheless, certain traditionally female-dominated sectors, such as merchants and market traders, have also played an important role in both the geographic spread and the intergenerational transmission of the language.
