Does cosmopolitan culture weaken ethnic and regional diversity: contraceptive behaviours of women in Istanbul, Turkey.

While Kurdish ethnic minority women were less likely to use traditional methods, compared with Turkish ethnic majority women, the difference might have been due to the length of time living in a neighbourhood. Regional variations in contraceptive use were concentrated only among Turkish ethnic majority women and for traditional methods. Regional norms of traditional method use may be a barrier to modern contraceptive use in Turkey.
