It is well known that women and men tend to work in different occupations, and generally held that this disadvantages women. In order to understand how far this occupational segregation entails gender inequality it is necessary to examine the vertical and horizontal dimensions of the segregation. The horizontal dimension measures difference without inequality while the vertical dimension measures the extent of the occupational inequality. Two measures of vertical inequality are used: pay and social stratification (CAMSIS). Measurements over a number of industrially developed countries show the expected male advantage with regard to pay. However, contrary to popular beliefs, women are consistently advantaged in terms of stratification. Also, it is found that the position of women is more favourable where the overall segregation is higher – the lower the male advantage on pay and the greater the female advantage on stratification.
