The new Sustainability Development Goals aim to ensure no one is left behind.

Over the last 15 years, there has been significant progress in reducing poverty in terms of income and in relation to health, education and living standards.

Yet, the experiences of different groups and individuals within countries diverge. And many of the poorest and most marginalised groups have not benefitted enough from progress.

The new SDGs explicitly recognise the disadvantages faced by certain groups and stress the need to leave no one behind. They identify a series of groups that are over-represented across several indicators of deprivation, including older people, people with disabilities, ethnic and religious minorities, women and girls, and sexual minorities, among others.

About a third of children out of school are disabled and people with disabilities complete fewer years of schooling on average.

Only one in five older people have a pension, according to UNFPA and HelpAge International, and this share is even lower in developing countries.

Further, all people belonging to a particular group do not experience exclusion equally. Intersections of group-based characteristics often overlap, leading to considerable disparities within groups.

The intention of this film was to illustrate the reality of the life of 4 marginalised groups of people, as a wake-up call to policy makers to increase their humanitarian efforts to ensure that no one is left behind.
