What does delta mean?
The Greek letter delta—Δ—is used in mathematics and science to signify the amount of change in a particular variable.
What is 8.7?
In Target 8.7 of the Sustainable Development Goals, States committed to take immediate and effective measures to eradicate modern slavery, human trafficking, forced labour and child labour.
What do they mean together?
Delta + 8.7 = Measuring the change towards Target 8.7.
On any given day in 2016, the latest year for which we have a reliable estimate, 40.3 million people were in situations of modern slavery or forced labour—or one in every 174 people alive —and 152 million children were victims of child labour. Urgent action is needed to address these problems. With Target 8.7 of the United Nations Sustainable Development Goals (SDGs), 193 countries pledged their commitment to take effective measures to eradicate modern slavery, human trafficking, forced labour and child labour.
But what are effective measures? What works to address these problems?
To answer these questions, the United Nations University – Centre for Policy Research (UNU-CPR) created Delta 8.7—an innovative project that helps policy actors understand and use data responsibly to inform policies that contribute to achieving Target 8.7. Delta 8.7 brings together the most useful data, evidence, research and news, analyses cutting-edge data, and helps people understand that data so it can be translated it into effective policy.
