I think first there is a need for building perspective of all stakeholders in developing countries on substantive equality when discussing issues of disability. That is people with disability have to be treated differently to achieve equality in development outcomes. Those who face multiple disabilities need special attention, as well as those with other marginal identities on the basis of race, caste, class, ethnicity, religion, location, sexual orientation etc
Second, countries could share how they identify people with disability, and build capacities of enumerators to do so, and challenges they are facing. Visibilising their existence is a must.
Third, sharing how services in developing countries are made accessible to people with disabilities, and being used equitably would be good
Fourth sharing legislation, policies and budgeting practices that are disability specific or inclusive would be good.
Finally sharing SDG monitoring from abilities lens would be good. After all, no one should be left behind
