Check against delivery disability, age, class, caste or other factors. Such multiple discrimination may affect these groups of women primarily, or to a different degree or in different ways than men. States parties may need to take specific temporary special measures to eliminate such multiple discrimination against women and its compounded negative impact on them”. In General recommendation No. 27 on older women and protection of their human rights, adopted in 2010, the Committee again addressed multiple discrimination and stated that discrimination experienced by older women is often multidimensional, with the age factor compounding other forms of discrimination based on gender, ethnic origin, disability, poverty levels, sexual orientation and gender identity, migrant status, marital and family status, literacy and other grounds. It stressed that older women who are members of minority, ethnic or indigenous groups, internally displaced or stateless often experience a disproportionate degree of discrimination. In order to support legal reform and policy formulation, it recommended that States parties collect, analyse and disseminate data disaggregated by age and sex, so as to have information on the situation of older women, including those belonging to minority groups and that such data should especially focus, among other issues, on poverty, illiteracy, violence, unpaid work, including care-giving to those living with or affected by HIV/AIDS, migration, access to health care, housing, social and economic benefits and employment.

In its most recent General Recommendation No 28 on the core obligations of States parties under article 2 of the Convention on the Elimination of All Forms of Discrimination against Women, adopted in 2010, the Committee again explicitly spelt out that intersectionality is a basic concept for understanding the scope of the general obligations of States parties contained in article 2 and that discrimination of women based on sex and gender is inextricably linked with other factors that affect women, such as race, ethnicity, religion or belief, health, status, age, class, caste and sexual orientation and gender identity. The Committee stressed that States parties must legally recognize such intersecting forms of discrimination and their compounded negative impact on the women concerned and prohibit them. It was again reiterated that they also need to adopt and pursue policies and programmes designed to eliminate such occurrences, including, where appropriate, temporary special measures in accordance with article 4, paragraph 1, of the Convention and general recommendation No. 25. The CEDAW Convention, being about the elimination of all forms of discrimination against women, not just discrimination based on sex, contains a very broad definition of discrimination against women in its Article 1, which addresses any “distinction, exclusion or restriction
