Occupation segregation by tracey adams and sandy welsh. Fox and fox argue that the decline in segregation was, at least partly, spurred by the movement of women into some formerly male-dominated occupations. Vertical segregation is occupational segregation associated with income inequality, while horizontal segregation means that different groups work in different jobs, often in different sectors of the economy, but that their earnings are likely comparable. Data documenting a drop in sex segregation in canadian society provide good news, implying that longstanding gender inequality in the labour force may be on the decline. Women"s employment continued to be less ethnically segregated than men"s because women"s employment tends to be concentrated into fewer job categories. People of colour are least likely to hold positions of status and authority. Many female dominated jobs pay less than many male dominated jobs. Some of the gender gap in wages may also be the result of other factors like age and discrimination.
