To reduce inequalities within and among countries.

• On average-and taking into account population size-income inequality increased by 11 per cent in developing countries between 1990 and 2010
• A significant majority of households in developing countries-more than 75 per cent of the population are living today in societies where income is more unequally distributed than it was in the 1990s
• Evidence shows that, beyond a certain threshold, inequality harms growth and poverty reduction, the quality of relations in the public and political spheres and individuals' sense of fulfilment and self-worth
• There is nothing inevitable about growing income inequality; several countries have managed to contain or reduce income inequality while achieving strong growth performance
• Income inequality cannot be effectively tackled unless the underlying inequality of opportunities is addressed
• In a global survey conducted by UN Development Programme, policy makers from around the world acknowledged that inequality in their countries is generally high and potentially a threat to long-term social and economic development
• Evidence from developing countries shows that children in the poorest 20 per cent of the populations are still up to three times more likely to die before their fifth birthday than children in the richest quintiles
• Social protection has been significantly extended globally, yet persons with disabilities are up to five times more likely than average to incur catastrophic health expenditures
• Despite overall declines in maternal mortality in the majority of developing countries, women in rural areas are still up to three times more likely to die while giving birth than women living in urban centres

Inequalities based on income, sex, age, disability, sexual orientation, race, class, ethnicity, religion and opportunity continue to persist across the world, within and among countries. Inequality threatens long-term social and economic development, harms poverty reduction and destroys people's sense of fulfilment and self-worth. This, in turn, can breed crime, disease and environmental degradation. Most importantly, we cannot achieve sustainable development and make the planet better for all if people are excluded from opportunities, services, and the chance for a better life.

An estimated 69 million children under five years of age will die from mostly preventable causes. Rural women are three times more likely to die while giving birth than women in urban centres. Many families in developing countries are living in societies where income is more unequally distributed than it was in the 1990s. These are just a few examples, but it is an issue that affects every country in the world.

In today's world, we are all interconnected. Problems and challenges, be they poverty, climate change, migration or economic crises are never just confined to one country or region. Even the richest countries still have communities living in abject poverty. The oldest democracies still wrestle with racism, homophobia and transphobia, and religious intolerance. A recent UNICEF report noted growing inequality among children in several high-income countries. Global inequality affects us all, no matter who we are or where we are from.

It can be and should be achieved to ensure a life of dignity for all. Political, economic and social policies need to be universal and pay particular attention to the needs of disadvantaged and marginalized communities. Recent statistics have shown that this is possible. From 2007 to 2012, the average income of some of the poorest families in more than 50 countries, particularly in Latin America and the Caribbean, and Asia, grew faster than their national averages, reducing the income inequality in those countries.

Reducing inequality requires transformative change. Greater efforts are needed to eradicate extreme poverty and hunger, and invest more in health, education, social protection and decent jobs especially for young people, migrants and other vulnerable communities. Within countries, it is important to empower and promote inclusive social and economic growth. We can ensure equal opportunity and reduce inequalities of income if we eliminate discriminatory laws, policies and practices. Among countries, we need to ensure that developing countries are better represented in decision-making on global issues so that solutions can be more effective, credible and accountable. Governments and other stakeholders can also promote safe, regular and responsible migration, including through planned and well-managed policies, for the millions of people who have left their homes seeking better lives due to war, discrimination, poverty, lack of opportunity and other drivers of migration.

International voluntary work plays a key role in delivering and implementing the Sustainable Development Goals as volunteering supports social, economic and environmental change. It is an important driver of civic engagement in the 21st century. If you want to do more than just join the conversation, Volunteer World provides the chance to become active and help reach the SDG Goal #10 Reduced Inequalities.
