For example, requiring a marriage certificate of all families registering in a social protection programme may discriminate against those families that are not formed by marriage. They cannot be exercised in isolation from other human rights such as the right to education, the right to the highest attainable standards of health, the right to an adequate standard of living and the right to privacy. All these rights greatly impact on the enjoyment of the rights related to the family referred to above, and vice versa. As shown by empirical evidence, increased levels of education for girls dramatically reduces the incidence of infant and maternal mortality; leads to smaller and more sustainable families (as women with higher levels of education have fewer children and more often use contraceptive methods); leads to healthier and better-educated children; reduces rates of child marriage; and increases family resilience to natural disasters and climate change.
