The ILO report noted global estimates where more than 100 million girls were involved in child labour, and many were exposed to some of its worst forms. This is in line with assertions made in numerous other references, which also point to a strong link between education, increased women’s (as opposed to girls’) labour force participation, the wages they earn and overall productivity, all of which ultimately yields higher benefits for communities and nations. In other words, it pays to invest in girls' and women's education. Anne Oakley in particular, is known for coining the term gender socialization (1979), which indicates that gender is socially constructed.
