Although women’s presence in occupations that are not “traditionally” regarded as suitable for them, particularly in the scientific and technical fields, is growing, it is still far from equal to that of men. Worldwide, women’s employment is concentrated in a relatively small number of branches of economic activity. This restricted presence contributes to creating stereotypes of women and excludes them from professions that are better remunerated. On the other hand, boys and men also tend to be corralled into occupations traditionally thought of as masculine – such as construction, engineering, finance, the military, and so on. They should also have equal access to the traditionally feminized professions, such as teaching, nursing and care work. Horizontal occupational segregation by sex has its roots, at least in part, in gender inequalities in education and vocational training systems.
